Solve : Intel Processor for Server and Workstations? |
|
Answer» HELLO, I WANT to know, what is a good processor for a server running Windows Server 2008 R2 SP1 and a processor for workstation running Windows 7? Finally, a MAC running Snow LEOPARD? thank you! I want intel!Almost anything. Servers were running years ago on CPUs that most users would now throw away. What performance level do you want? Do y0ou have a giga bit connection? Is this a business venture? Is cost an issue? Budget ? ? Quote from: patio on October 18, 2011, 05:31:28 PM Budget ? ?Very important question. Quote Lease-to-Own Server -- $49/month:So that would mean anntel Xeon E3-1230 is a good basic server CPU. But that might not be a good choice. That is why I added more questions. The Xeon is the best choice for certain applications. The OP needs to be more specific about objective.Hmmm, concerning cost, no major problem! I want a good intel processor so that it can run the Windows Server 2008 R2 without problem. And the workstations connected with it as well. On the workstations, I can put Intel i7 becaue some compouters will have VmWare. Only the server I'm a bit hesited, whether to buy Xeon, or i7! The server will have 8GB RAM, internet speed 4MB!OK. The Xeon is a dead end. Go with the current Intel family of high-end CPUs I only mentioned the Xeon because it is a cost-effective solution at the present time. But it is old technology. http://en.wikipedia.org/wiki/Xeon Here is what Intel is doing now. and coming soon. http://en.wikipedia.org/wiki/List_of_future_Intel_microprocessors Any advances in software nwill target the newer CPUs. So if you ever wamt tp upgrade yhour software, you want the new generation of Intel processors. Yes, some i7 CPUs are part of the 'Xeon' family, but I meant the older Xeon. Intel i7 is what you want. Good capital investment. (But you can buy a USED old XEON dual-core server for $120, keep if for a year and throw it away.) so I can put Intel i7 then? If yes, then its good! Thank you! Now, have to search a good MOTHERBOARD... |

Solve : Video card compatibility? |
|
Answer» I got a HP Compaq dx2200 : ...And right now I will try to put it in the PCI slot maybe it will work...Nope, it will only fit in 1 type slot, PCI is not PCI-e.doublin, If not already too late STOP. If you try to insert the PCI-E card into a PCI slot the worst case scenario is that you will damage the slot thereby eliminating it future use for anything--also you may damage your card (which may NOT be damaged at this point). These 2 slot types are NOT interchangeable. Is the PCI-E card a new product with all it's software and documentation? Is it still under warranty? truenorthMake it fit. Yea,I took a look inside there and didn't took me too long to see that it will never fit in the PCI slot The card is not new.I had it dumped in a box along other old pc components for a long time.It's just that the video card that I was using now got fried, and I thought I could use this GeForce instead of the onboard video, untill I buy a better one. Seems like it broke after all this time staying in there, scratching with all the other pieces. Thanks to all of you!At least you have a backup video with the onboard. The graphics card fans are the weak link. Nowhere near the quality of a CPU fan. Can't expect much of a $50 card. Not sure if the expensive ones have better fans.One more thing. On this website http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/12454-12454-64287-321860-3328893-1844701.html if you click Specifications and scroll down to Graphics and Input/Output devices you can see that it says: Graphics cards Integrated ATI graphics processor derived from the Radeon X300 ATI X300 PCIe x16 Graphics Controller ATI Radeon X1300 256 MB DDR PCIe Graphics Controller Does that means I can use only ATI video cards? :/No, you can use any (any brand) PCI-e graphics card. All the models say: Integrated ATI graphics processor derived from the Radeon X300. The GPU's are ATI & nVidia. While those 2 make their own cards, many manufacturers use the GPU's on their own cards. I happen to have EVGA which uses nVidia GPU chips. The main issue is the Power Supply (PSU), it's only rated at 250W, but read the nameplate for the +12VDC, since that's what the graphics card uses. Most graphics cards will state their requirement for the 12V. You're probably looking for a lower end card since that's all your PSU will support. Depends on what you will be using the computer for.Does the card have a 4 pin white female slot on it ? ? Does your PSU have a male 4 pin plug ? ? If the card does have it then it's required for it to run...Never mind,solved the problem.I threw it back in the box and ordered a new one from Ebay. Thanks all of you for your time. |

Solve : Intel Processor 32 Bit, who knows a good one?? |
|
Answer» Ok, I did post a QUESTION like this before, but now I'm in a real dilemma, I want an Intel Processor 32 Bit which can support Windows Server 2008 R2 and some workstations which will have VmWare installed, can you suggest me one? I have gone on Intel website, I'm seeing only 64 bits there, but I want one for 32 bits! Thank!Intel's 64-bit processors also execute 32-bit instructions. The last processor that was purely 32-bit to my understanding was the Pentium 4 (or MAYBE Pentium D)Can you give me a good Intel i3 or i5 to support my software I mentioned above? I have cheked all, but confused! Quote from: angel2011 on October 20, 2011, 01:48:11 PM Can you give me a good Intel i3 or i5 to support my software I mentioned above? I have cheked all, but confused! What motherboard is this going in? There are different socket types.. What is your budget? What else is the PC going to be used for?You seemed to be satisfied with the replies in your other Topic... Are you 2nd guessing the advice...or your choices ? ? I guarantee if you provide WAY more details on what you want to accomplish here you will WIND up with more QUALIFIED responses...Well, I don't have problem with the budget. Socket, maybe 1366 is ok. The only problem here is I'm confused which to choose among these motherboards of i7 series on Intel website! I'm going to install Windows Server 2008 R2 on one machine and its 32bits. I will put only 4GB RAM as its 32bits. The rest of the machines will have Windows 7 and VmWare to run different operating systems like Linux. that's all! Problem, I'm confused which to choose! Well it's a bit clearer... Just because you are going to use an i7 InTel CPU does not mean you are limited to only InTel MBoards... Some i7 MBoard reviews NewEgg's i7 MBoard choices... Hope this helps...For the server, I'm buying this: http://ark.intel.com/products/52213/Intel-Core-i7-2600-Processor-(8M-Cache-3_40-GHz)#compatibility For the workstation, it's this: http://ark.intel.com/products/53428/Intel-Core-i3-2130-Processor-(3M-Cache-3_40-GHz) For motherboard: http://www.asus.com/Motherboards/Intel_Socket_1155/P8P67/ What all of you think? |

Solve : second CD drive? |
|
Answer» I have a pryon desk top with Windows 7. The tower appears to have two CD DRIVES but we have only used the top one (D:) to date. We have been unable to open the lower one. Help says there is only one hard disk drive. Does this mean that if we wish to make use of the SECOND drive we have to buy the hardware and instal it. And would we use a second drive for copying CDs and DVDs.It sounds like you may have one CD drive and beneath it is an empty drive BAY with a front cover on it. Is there any writing on the front of the second, lower "drive"? |

Solve : Overclocking i7 920? |
|
Answer» Hello all, I just have a QUICK QUESTION. Is it better to overclock a i7 920 to about 3.6 with water-cooling, or to buy a new processor?Also, If i do overclock it, does the memory frequency and voltage requirement for the memory change?I have a i7 930 overclocked to 4.0 and I have had no problems at all, but it's up to you to decide if you want to overclock. I say this because OVERCLOCKING can LEAD to damage if not done correctly and I don't think anybody would want to be blamed for giving you the wrong information. |

Solve : VHS to DVD? |
|
Answer» I have a bunch of VCR tapes and would like to copy them to DVD. I picked up a Roxio easy VHS to DVD. I copied three movies and they didn't copy the sound. Any ONE know any thing about this stuff? It is all hooked up the way they said to hook it up. USB to the computer and the colored connectors to the same color on the out of the VCR. Then do what your told. The moves look good they just don't have any sound. Thank you much for your time.I also have one of these devices that I used to convert Sony Hi8 aka Super 8 to Digital format. Mine is called EasyCAP. Or lack thereof. With great effort, I managed to track down the Vista version of the driver, which worked passably on Windows 7. If you then track down some windows 7 compatible third-party software (currently using Media Player Classic to watch live, Debut VIDEO capture to record), you can view and record footage. Mind you, it s not very good footage. And the brightness/contrast is off, so colors bleed and are faded. What OS are you using? And what is the exact model # of this device such as Roxio NP-640 etc?I can't find a number on the box. It is called,( easy roxio VHS to DVD ). I have gotten a hold of support and they are saying that they are WORKING on it. As of yet no help. Every thing works but I have no sound. The thing came with a DVD that has all the stuff on it that makes it work. I loaded it. Like I said it works yet no sound. I am using Windows XP. Thank you much for your time.As you are just embarking on this project i SHALL give you some of my impressions from having done hundreds of them. Firstly i am NOT happy with the picture quality particularly if you use a compression format so as to get more than one vhs movie on the disc. I found the more (up to 4) you put on a disc the worse they all are. Whatever you do do NOT put paper labels on the disc. I bought 2 different brands of direct vhs to dvd player/recorders once i found i was not satisfied with the computer based process and was still not impressed with the picture quality. I gave up on doing it.truenorthInteresting discussion. I have been using a product called DAZZLE since late 2007/early 2008 to convert our 'home videos' to DVD. It is a small device which plugs into your VHS recorder/player and to your computer via USB. Follow the setup and run instructions and it works ... AS THEY SAY IN THE MARINES "WORKS FINE, LASTS A LONG TIME, DON'T RUST!" Semper Fi ... & regardsDazzle is what I had first. It would copy to the hard drive but then you had to down load to a DVD from the hard drive. That would take twice as long. I have like 200 VHS tapes to copy to 200 DVDs. Still no word from support. I think I am going to take it back and try and get the MACHINE that will do. I was told that they make a machine that will do it. I have not found one yet. Any one here know of one or where to buy it?Btw, I have tons of VHS tapes so what should I do? I hate that VCRs are becoming extinct I do have tons of VHS tapes like said. Wouldnt it take a lot of money to transfer them to DVD because you have to buy the DVDs. I do think there are a few VCRs with a DVD player with them. |

Solve : New HDD Failure After Replacing Old One? |
|
Answer» I recently experienced some problems with my computer. After running Dell and Norton diagnostics both came back as hard drive failure. I purchased a new hard drive and had a professional install it. I installed the OS and drivers from the Dell disks that came with my computer. The computer was running fine after installing Microsoft Office, QuickBooks and Norton, downloading Java, Adobe and Blackboard IM. Windows then performed a 104 MB update. When the computer was re-started it started a Windows Configuration. It only made it to 30% and then froze for over an hour. I restarted the computer and Windows was able to restart and complete the configuration. Once I was logged in to my computer Windows Explorer continually froze or was super slow. I restarted the computer and it will not start normally. It mandates that I launch system repair and takes me to the System Recovery OPTIONS. From the next screen I am only able to restore computer using a system image created earlier. It is not recognizing my computer as having an operating system and I cannot restore from a system image because there is none. I ran the diagnostics TOOLS off of the Dell Driver and Utilities disk and from the Dell screen (F12). Both come back as telling me there is HDD errors. I am familar with computers but I don't know a lot about the inner workings of them so please feel free to simplify repliesNew systems, like the old on es, still requires backups. Especially before you do an update. This is about XP SP2 to SP3, but hoods true for any large update. Error recovery from a bad download is still a weakness in the Windows OS. MS recommends Backup before major update. This can even apply to Vista and Windows 7. http://support.microsoft.com/kb/950717 A new install from scratch should cure the problem. Quote from: snuttman97 on October 23, 2011, 11:10:33 AM ...I am wondering if the problem is really with my HDD or if it could be the motherboard or Windows itself.Maybe needs a BIOS update.

Solve : gateway desk top? |
|
Answer» I have a gateway DESK top that's only 3 years old. I have not used that pc in a while because of laptop. I started using the desk top again, I did a full system restore and everything WENT fine until the next morning when I tried to turn the pc on, when I pushed the power button it would not turn on, however as I pushed the power button at the same time the FANS would come on until I let go of the button. A friend told me to replace the battery inside the gateway on the mother board. I replaced it by unplugging everything then installing when I went to turn it on only the fans came on and they would remain on. Only way to turn off is by unplugging the pc. |

Solve : INSTALLING WIRELESS ADAPTER? |

Answer» (Compaq Desktop Pc / Windows 7) See something here that looks like what you want to get?Well, if that link won't create some confusion, then nothing will. The smorgasbord of wireless adapters. Felt it to be QUITE appropriate due to the general nature of the inquiry--perhaps if the O/P finds his/her choice from the "smörgåsbord" we may need to be more SPECIFIC with our answer. However my answer after that pretty much fits them all--i doubt the choice will be one of the more elaborate ones anyway.truenorthThe original post is vauge, with very little information. But the question asked is 'how to install a wireless adapter' - Not which wireless adapter to "buy". THEREFORE that's why I asked the questions that I did. If the O/P needs a list of available wireless adapters available, then he certainly has it. Thanks for the extensive list truenorth. Where are you lewy? More iformation is NEEDED. |

Solve : Multipal start ups followed by a flickering screen during bootup? |
|
Answer» So I press the power button and turn my pc on. the pc is on for all of 4 seconds when it shuts down and then turns back on. this happens three times followed by a startup success however when It goes to the "loading page" my screen goes black and I have to restart the pc. this all occurs about three to five times before I can actually successfully get on. on a side note Once its succesfull for the first time I can turn off the pc and tur it back on and It works like a charm. on some occasions the monitor will not even turn on. Id love it If someone could help me with this? It goes to the "loading page" my screen goes black and I have to restart the pcLaptop or Desktop? Post as much details to your computer such as model/brand. Do you see any ACTIVITY(led lights) from the HD loading/reading while its on blackscreen? Any previous issues that might have cause this behavior or recent changes to hardware or software?One cause for random reboots is that the computers processor is getting too hot. To CHECK this, enter the computers bios during boot (usually by pressing Delete, F1 or F10 when the computer just starts) and there will be an option about the computers temperature (often under “PC Health”). This should show you the CURRENT temperature of the computer and the emergency shutdown temperature. The emergency shutdown temperature is a safeguard for when your computer gets too hot it will shut itself down to prevent damage. You can either raise the shutdown temperature or switch it off completely, however be warned that you may damage your computer (or the clients) if the computer gets too hot. If the temperature was causing the reboots then you should consider getting better cooling for the computer such as more powerful CPU fans and more case fans. http://www.techyv.com/questions/windows-wont-start-normally-keeps-restarting#commentsWhy are you plugging this Help site when that's what we do ? ?

Solve : graphic card dying?? |
|
Answer» Hello, What I am suspecting, is some kind of "degenerative disease" of some component of the graphic card, that would be exacerbated by overheating. That sums it up. You tried drivers and it did not really resolve the issue. Dust and heat can cause permanent damage. On not. Here is something you can try. Bit the laptop in your refrigerator for an hour. Cover it so that moisture will not enter. DO NOT let the laptop get down to freezing. About 50 F or 10 C is enough. Now turn the laptop back on and notice if there is a noticeable improvement in normal boot mode. If so, then yes, it is a over heating problem. The logic to this is that it will take longer for the GPU to get to the critical temperature where is fails. This is not a cure. Your GPU has a thing internally called 'thermal runaway' and happens after damage is done to the silicon. If it was a desktop, could try extra cooling, but not easy to do on a laptop. Here is a video. This guy says it is easy. I don't believe it. But see for yourself. How to remove and install a laptop graphics card. (Part 1) Yes...Someone on the chat suggested that I should also use a better paste that the one I used when replacing the thermal cooling assembly (a silicone paste, white in colour: better use arctic paste?). I will do both of them at once (the paste and the fridge), and yes, maybe it will start in a better way. What I do not understand yet, is how a GPU can be damaged (irreversibly damaged) but still work sometimes. Is it a matter of the distance between conductors, that allow tunneling effect at higher temperatures, but not on lower ones, and the max temperature getting lower and lower? So it seems this laptop is beyond durable workaround. It will teach me 2 lessons: first, get 5, not 3 years of warranty, and second: clean your fan more often! Thanks for the reply, it puts words on it! And by the way: I cannot replace only my graphic card, as it is integrated together with the motherboard, on the same card! And the GPU chip cannot be taken off on my motherboard from what I saw...maybe I'm wrong...Dell Latitude D830 motherboard is about $200 as a used or refurbished item. They have a limited warranty. The CPU has built-in protection to prevent thermal runaway. Plus it has a fan. And you can replace the CPU. The Graphics processor should not generate as MUCH heat.Dust will shorten the life. Dust impends air flow. Tao bad they don't put fans on laptop GPUs. Maybe soon we will have mobile devices with better thermal control. Are you interested in Thermal runaway? Some of the research gets kind of deep. Here is a sample of what they want to do: Quote Abstract— Preventing silicon chips from negative, even disas-Pretty heavy stuff. EDIT: That link is hard to find. Here is another that sounds like your problem. Notice they focus on the CPU and ignore the other overheating issues, such as the GPU overheating. http://www.howtofixcomputers.com/forums/dell/dell-inspiron-1525-overheating-296811.htmlAbout motherboard replacement, I came to the same conclusion: it costs far less than a new laptop, and if I use good thermal paste with regular cleaning of the fan, my laptop should last this time. The problem is: I am afraid of compatibility issues. Like: will my processor (T7500 core 2 duo) fit on every D 830 Motherboard? will the GPU always be aligned with the cooling assembly I have? Will it always support my WSXGA+ screen (1680x1050)? On all the links I saw, the said nothing about such compatibility...And I cannot make dell tell me the dell part number of the motherboard I already have (this way I could be sure). Is there a spot on the motherboard, where this part number could be written? Or some hardware recognizing utility on the web? Once I am sure, I buy the motherboard, the thermal paste, and then pray whatever computer god that all my guesses were right... BTW thanks for the link :-)In my opinion you are throwing money away resuscitating a laptop for any reason and looking down the road for things to get better or stay the same is wishful thinking at best... Others here may have differing opinions however...I have thought about that. Although this laptop is old, it has a lot of advantages, modern "cheap" laptops lack: - a good screen with good resolution, good refresh time, very clear, you can see everything _ really everything _ no matter what angle you are looking at it from; - not bad calculating power - The Gpu, when working, can cope with 60 fps HD videos, works well with Cinema 4D and other stuff, - the system is still XP and works well (I have some science computing software that would not work on Seven) - I recently purchased a second battery - and...I won't have enough money to buy a new good one, before 2 months! Because of a hole of 3 months with no income at all...and this computer is also kind of my workstation (I have a computer at work, but a PC: I like taking my data with me, like in the train as I travel every weekend, or at home, and I have no PC at home!) And compared to all that, now I understood the problem that killed this laptop, for like 200$ I could refurbish it...if I find something trustful, why not!EDIT: after a useful lshw command on a live cd I have (pretty useful command, this is), I knew everything I needed to know. From my motherboard part number (OHN338: apparently Google too hears it almost for the first time, and never heard of resellers), to the true name of the enemy inside my PC: the G86M chip. By browsing about that I found a lot of complaints about overheating, even someone who had his motherboard changed 5 times because of that by dell (he had warranty of course), until I stumbled upon this: story don't know how reliable this is, but this might explain a lot...about precision laptops failing the same way etc...or maybe it is just today's laptops that always want a too big graphic performance for the cooling and thermal stress they can afford...So, maybe you're right about that motherboard stuff, maybe it's still too much money for what it is...I will keep searching just in case, and just to try out, but this is quite embarrassing...I did not want to buy a cheap computer just to link today and in 4 months time when I will have all the money needed to buy a true good laptop...But *censored* if I can live with no PC for all this time!Thanks for sharing your research. The reference implicates that you will have the same issue again with a replacement motherboard. It seems THET the designers did not pay enough attention to thermal design. Here a a partial quote of the three-year-old article: Quote All Nvidia G84 and G86s are badQuote from: patio on October 27, 2011, 02:51:53 PM In my opinion you are throwing money away resuscitating a laptop for any reason and looking down the road for things to get better or stay the same is wishful thinking at best...If you can fix it for less than $100, then OK; otherwise, I agree with patio, new laptops have never been cheaper. |

Solve : memory cards? |
|
Answer» :(Although the maximum memory for my DELL dimention 2400 is listed at 2gigs my machine will not boot up with any more than 1gig. I have the model compatible cards from Crucial , is there some changes needed in the bios I should be making?. The O/S is windows XP service pk 2.Do you actually have 2Gb of ram installed? Just because that's the maximum it will handle does not mean it has that much installed.I currently have 1 gig installed and the computer boots up normally but if try to add any more memory it willnot boot even though Dell says it will take 2gigs. System info recognises the 1 gig .So i gather the computer up until your decision to increase to 2gb has up to now always had 1 gb and worked properly? That being so you do state " I have the model compatible cards from Crucial " in reference to what i assume is the additional 1gb ram you PURCHASED. In the event that it is "compatible" as stated by Crucial still leaves the possibility that is NOT in fact the same MANUFACTURER and/or the exact same model as the original 1gb. That can be the basis of your problem. Also does the single "compatible " module WORK on it's own in the computer? If not EITHER it is NOT compatible or is defective. truenorth Dell says 2GB, but they also say modules up to 512MB & it has 2 slots. Usually, this is because 512 was the largest available at the time. In your case, it appears that 512 is a real limit. |

Solve : Refresh rate and FPS I'm confused.? |
|
Answer» Hi, i have just purchased a 23" Asus 3D monitor that has a refresh rate of 120hz and so is capable of running games well over 60fps with vysnc on. The problem I have with this is people keep telling me the human eye can only take in 60 fps in games and so I'm wondering what benefits there are for having a monitor with a refresh rate of 120hz? Please only answer this question if you know something about this subject because I am thinking of taken this monitor back and exchanging it for one with a refresh rate of 60hz. Does the 120hz maybe have something to do with the 3D? people keep telling me the human eye can only take in 60 fps in games "The human eye cannot detect more than X FPS in games" is an inherently flawed statement as humans are not digital machines. The human brain is always on, always receiving input- it doesn't see "frames". Light HITS our eyes as a wave, and the information it carries is almost instantly transmitted to the Visual Cortex. The brain analyzes this data, focusing on CHANGES brought on by motion and fluctuations in intensity. Displacement is interpolated via motion blur and identical input is discarded to avoid extraneous processing. Basically, what we see is mostly dictated by "video post" filters that take place in the brain. The “decoded” image is further analyzed by various parts of the brain, but the overall process — as complex as it is — is quite fast and versatile. Much faster than 60 fps. The main reason for this myth starts with the older "can't see more than 30fps" myth, which exists because most video formats are 24-30 fps, so people assume that value was chosen based on some sort of opthamalogists recommendation or some nonsense. It wasn't. The reason films and movies get away with 24fps is simply because they have things like motion blur in-frame that assuage the brains sensation of motion. not always accurate, and in many cases purposely exaggerated to create a distinctive visual effect. The processing of such motion blur effects lowers the framerate even further, anyway, and that is noticable at an input-level. More granularity helps to smooth out movement and the human eye has no upper limit to "Frames per second" simply because the human eye and Visual Cortex have no concept of a "frame".

Solve : Overclocking Temperature and Nvdia Sparkle GT-240? |

Answer» My PC is
THANKS to whoever tries to help :3Crystal Disk will run the cars flat out thru various tests...if it crashes it's most likely the card... P.S. the info i read on the card said although a PCI-e card no external power is needed.Crystal Disk Info Crystal Disk Mark 3.0.1 500W is more than sufficient for the GT 240. "Suddenly things are like invert colors" Does this happen with your onboard GPU? Were you overclocking when the issue occurred? How much did you overclock from stock settings? Can you run Furmark and do the 720p preset benchmark to stress-test your GPU? "How do I make sure the processor is not used for graphics?" It depends on the game-some poorly optimized games like CRYSIS put a full load on both the CPU and the GPU. If your game supports nVidia PhysX you might WANT to set your graphics card to render PhysX effects, not your CPU. |

Answer» Hello, again. My printer doesnt work. When I try to print something out, internet explorer SHUTS down the program. Now I can print documents that I type (Mircosoft Word, PROCESSOR) but I cant print any documents from the Internet. I have a Lexmark 3500-4500 Series printer. I bought it when I bought my COMPUTER back in Nov. 2007. Now, some of you may know, I had a major problem with my computer and I did an eRecovery which wiped out everything until I got it back which is for another topic. My point is I cant print any documents. Please help!!!You need to check and see if Lexmark printer is set as the DEFAULT printer. Well, this morning I had to print some stuff and my printer worked!!

Quote from: nickgr5 on October 23, 2011, 12:17:05 PM Just a moment; do you connect the HDD while the system is already running? I wondered that myself; if so, worst case is 1 dead hard drive and 2 dead motherboards... as amritpalpathak post, PC can run with Live Disk. many reasons here. 1- check your data cable (SATA/IDE) of HDD. un-plug data cable but plug power one. if your system start normally, the problem is your data cable. so, check your data cable and data port on Mother Board. 2- check power cable of HDD. try another power cable 3- plug data and power cable to HDD, but do not install it in the case. hold it in your hand carefully and from its side. when you power on, if it shuddering for seconds, your HDD may stile healthy. if not, your HDD maybe dead. Hi What make and model of hard drive. Some models have over voltage protection that when it is activated shorts the rail where the fault occurred. If the power supply is outputting the correct voltage you can remove the shorted component and then transfer the data to a new drive. Hope to hear more information soon Lisa Quote from: amritpalpathak on October 23, 2011, 03:22:27 AM I tried it by connecting to other computer but still samppe haened there. He said that he has tried it on another computer. I presume "samppe haened" means same happened there. For that reason I'm guessing it's the HD if he didn't use the same cables on the other computer. As for the vote, I thought a Hd was a Hard disk, so I didn't vote.Meanwhile he's been abducted... |

Solve : CPU heat sink to fit my motherboard? |
|
Answer» I have a GA-EP45-UD3P motherboard and I am searching for a good heat sink for my CPU. My CONCERNS are the 3 heat sinks on the motherboard getting in the way of a larger CPU heat sink. I have been playing BF3 and have noticed my CPU has hit as high as 90C which is causing me some concern. Have you tested the temp with the side panel off so that you know its truely the CPU heatsink and not a heat build up issue within the case itself? I have rarely seen where a heatsink cant keep a CPU cool and have it be due to the heatsink itself as the cause, unless the heatsink is under-rated for the wattage of the CPU and/or the CPU is running overclocked to cause an excessive amount of heat than in native clock. If you find that the temp runs cooler with the side panel off, then all you need to do is add positive or negative airflow in your case so that the CPU heatsink fan isnt recirculating the air creating a hot air pocket and causing the CPU temp to climb. Ill test that tonight, I currently have two 120mm front intake fans, a 120mm side panel intake fan, a rear 120mm exhaust, and a top 140mm exhaust. If I turned the side 120mm into an exhaust do you think that would HELP? |

Solve : Computer Upgrading Concerns? |

Answer» Hi Everyone, 2. For my RAM I prefer the Vengeance but it has a 1600MHz frequency while my card only supports 1333 MHz. Regarding this, any opinion?I don't know about Vengeance off the top of my head, but the XMS3 I bought for my machine is 1600. When I first put it in I forgot to set it to 1600 instead of 1333, but it worked normally for almost a week before I noticed the speed in the POST and changed it. Quote from: jackjimson on September 12, 2011, 05:59:29 AM Sorry forgot to add that.You didn't say what the goal of this upgrade is? Or why you want to upgrade?quaxo Ahh ok. Thanks for the reply. Quote from: Computer_Commando on September 12, 2011, 06:53:58 PM You didn't say what the goal of this upgrade is? Or why you want to upgrade?Sorry for not including that. My goal to improve my graphics card to run the newer games more easily on the higher settings.Thanks for the previous responses. One final question though. So I'm going with 2x4 GB modules of corsair xms3 (cmx4gx3m1a1333c9). What I'm wondering is if should mix it with my current ram (CM3X2G1333C9). They have the same manufacturer (corsair) but older, albeit the same, model. Do you think this is a good idea? Are there any drawbacks? Btw I'm using the stock/default settings on my rig. No part is overclocked.You won't have any problems mixing RAM in pairs. I've never had a problem mixing singles, but the specs must be identical, if they are dual-channel. If not, they won't function in that mode. My laptop has 2 4GB modules from different manufacturers & it functions dual-channel. You originally asked: "For my RAM I prefer the Vengeance but it has a 1600MHz frequency while my card only supports 1333 MHz. I assuming it will go down to 1333 but will it rub smoothly? Is it advisable to get this? Or just go with XMS3? " It should work at the lower frequency, but you need to verify this with the mobo manufacturer. It's a possibility that the Vengeance RAM won't work at all. Based on this: http://www.intel.com/support/motherboards/desktop/DP55WB/sb/CS-030682.htm I would not get the XMS3, if it meets this criteria, DIMM Capacity//Configuration//SDRAM Density//SDRAM Organization Front-side/Back-side//Number of SDRAM Devices 4096 MB // DS // 2 Gbit // 256 M x 8/256 M x 8 // 16 "DS” stands for double-sided memory modules (two rows of SDRAM). Quote from: Computer_Commando on October 04, 2011, 05:34:50 AM Based on this: http://www.intel.com/support/motherboards/desktop/DP55WB/sb/CS-030682.htmHi Computer_Commando, Thanks a lot for the response. I won't get vengeance anymore. My rig can't optimize it anyway I think. I would just like to clarify something though, I should NOT get XMS3 if it meets the specified criteria? Sorry, I'm just a little confused (since based on the link) the criteria you mentioned appears under "Supported DIMM configurations". Reference: XMS3 — 4GB DDR3 Memory Module (CMX4GX3M1A1333C9) Ok. So I have already completed the upgrade although it didn't go exactly as planned. For the GPU, I didn't encounter any problems. Everything is working as expected. However for the RAM, my initial plan of 2 x 4 GB XMS 3 didn't work (in addition to my initial 2 x 2 GB XMS Config). Unfortunately, I didn't have the foresight to bring the manual of the MOBO at the time of the install to diagnose using the beep code. I had it installed in a shop (too paranoid to do tinker with the hardware, still have to learn more). We tried different configurations: Config 1: 2 x 4 GB + 2 x 2 GB = Did not work. Config 2: 2 x 4 GB = Did not work. Config 3: 1 x 4 GB + 2 x 2 GB = Worked. Config 4: 4 x 2 GB = Worked (My current config). What I'm wondering is why didn't the first 2 configurations work? I'm a little stumped. The board specs indicated that it can support 16 GB of memory but could not handle 8 GBs? I tried scanning through the manual and the specs of the memory but could not find the reason why it didn't work. Anyone has any ideas? Just something to start my search on. I don't know where to start. I can't change my current configuration anymore but I want to know the cause of the problem so I don't encounter it again in the future. (I plan on making a new rig in 2 years) Quote from: jackjimson on October 22, 2011, 05:47:24 AM ...1. You did not read the specs carefully in the link I provided previously. The above configurations do not have enough information to determine why they won't work. Intel is very specific about the type of Supported DIMM: http://www.intel.com/support/motherboards/desktop/DP55WB/sb/CS-030682.htm Note the organization of the chips on the DIMMs & the organization of the devices noted in the 1ST table on the link provided. 2. I have not seen these specific requirements since my 10 year old Pentium III with SDRAM requirements for high density vs low density. By the time you're ready for a new rig, you probably won't have the same issue. DDR3 will be mature by then. [regaining space - attachment deleted by admin] Quote from: Computer_Commando on October 22, 2011, 07:57:26 PM 1. You did not read the specs carefully in the link I provided previously.I did read it, unfortunately, I did not properly comprehend. Still learning COMPUTER hardware Please bear with me. Quote from: Computer_Commando on October 22, 2011, 07:57:26 PM Intel is very specific about the type of Supported DIMM: http://www.intel.com/support/motherboards/desktop/DP55WB/sb/CS-030682.htmAre you referring to the density? The density of the SDRAM Density is incompatible with the board? Is this information generally available on a vendor's website? I tried searching Corsair's site but I couldn't extract this info. Yes, it's a density issue, appears to be not compatible. I've never seen memory manufacturer's specify this. Most motherboards are DESIGNED so chip density is not an issue. Don't know why Intel did not take this into consideration. They probably outsourced the design or gave it to an in-house designer who was a new hire & didn't fully understand. They were probably testing RAM compatibility & then found out, therefore, the chart noted. Only some at Intel would know & you will never find out who & they will never admit their error. |

Solve : Laptop Using wrong Video Card? |

Answer» I am currently using a very expensive HP laptop with 6G RAM, 2.0 GHZ i7 CPU, and a Radeon (TM) HD 6490M graphics card. But for some reason, when I do a system scan of my computer, all it says is that I am using the integrated HD graphics, and thus my games are hardly running. When I go into my device manager, under the Display adapters it says that I have the HD 6490 as well as the Radeon HD Graphics. I also tried to go onto the Radeon site and update the drives but it says its not compatable and I need to contact HP to get the mobile versions of the DRIVERS. Can someone please help me? I payed $1800 for this laptop so I could run games on it, but I can hardly run anything, including older games.Maybe its too late but I would have invest on a desktop for gaming for that price. Anyway, is there a switch to toggle on graphics or does laptop automatically recognizing the video effects? As looking on a specific dv6t HP model here http://www.mylaptopreview.com/Laptops/HP/2011/0617/HP-Pavilion-dv6t.html The dv6t has switchable graphics, featuring both an integrated INTEL HD 3000 Graphics chip and a discrete AMD Radeon HD 6490M Graphics chip with 1GB of dedicated memory. While not as useful as Nvidia's Optimus technology, which automatically switches between GPUs based on individual applications, the dv6t can toggle between the cards as a power-saving measure, asking users if they'd like to switch to the AMD card when the dv6t isn't plugged in. Also unlike notebooks with Nvidia Optimus, the screen blinks a few times during the transition.I was in need of a laptop for my current schooling situation, otherwise I would have gone with a laptop. The laptop is a dv6t I believe, but I have never received a message asking if I wanted to switch to the other card. Would you know where I could find the setting to manually change it?http://h10025.www1.hp.com/ewfrf/wc/siteHome?cc=us&lc=en |

From the pic, it's hard to tell how it's supposed to look like when new. Black connector on left goes to drive. Does the section on right go to the ribbon cable? Put it back together the WAY it's supposed to look. Hi thanks for the reply, The contact on the Black connector had been mended before but has broken again and i don't see how i can mend the strap as it is split. Roger. I don't see any contacts on the black connector; how does it mate to the other half? Usually notebooks have a special interface on the motherboard; the cable is an adapter; yours doesn't look special. Put it back together the way it's supposed to look, then take a pic. You image is not showing. You can upload directly to CH. See additional options below message reply box.Hi Hope this helps [regaining space - attachment deleted by admin]Your other pics are gone now. If you have the skills, this can be fabricated with this, which would replace the "split" ribbon. The broken contact on the pc board can be soldered with a small 28ga jumper wire.

Photoshop CS5 (and possibly PREVIOUS versions) use OpenGL to display their workspaces, but all filters and actual MANIPULATION of bitmap data is done in software. The actual card being used is not an important factor. As long as it supports basic OpenGL (and you would be hard pressed to find one that doesn't) it will work perfectly fine. Versions before they started to use OpenGL, and it won't matter, since all bitmap modifications and filters (with very few exceptions, aside maybe addons) were in software. |

Quote after I had disconnected the power cable from the HDD and turned the PC on,I sit corrected...Could be a CD drive. The OP should start the machine with the cover removed and observe (watch and listen) carefully. Quote from: Salmon Trout on November 03, 2011, 12:52:34 AM Could be a CD drive. The OP should start the machine with the cover removed and observe (watch and listen) carefully. Agreed. It could simply be a loose component being vibrated by a fan, or if the PSU has had heat issues the fan in the PSU itself and the rebooting could be due to a faulty PSU.one more strange thing I have to mention is that when I plugged the power cable of the computer to the power outlet, my PC would immediately turn on even if I had not pressed the power button. Is it related to CMOS problem? My computer clock is sometimes wrong and I need to update the computer time by "time.windows.com" My first thought was a cable touching a fan. Quote My computer clock is sometimes wrong and I need to update the computer time by "time.windows.com" That is a CMOS problem. Prob need a new battery. Quote one more strange thing I have to mention is that when I plugged the power cable of the computer to the power outlet, Many comps are set to boot up after power failure, so if you just unplug your comp to turn it off, that's probably why it starts up like that. There is USUALLY a BIOS setting that controls this. Something like 'power after failure'. |

The laptop went into sleep mode and I pressed the spacebar to turn it back on, but it just went to a black screen. I held the power button to turn it off and back on, but it just goes to the "Asus gaming series" screen and does NOTHING.

Solve : WD My Passport 070a Freezes Computer? |
|
Answer» I have an external Western Digital My Passport Essentials 070a HDD and I have a lot of critical data/backups on it. I recently, just after having connected it via USB, saw Windows notifications of "Delayed Write Failed" for almost every folder on the drive. I received 40 notifications before someone who was walking a little too close pulled the plug. After that, when I tried to connect the drive to the PC, it freezes, even my mouse becomes nonresponsive. This is my school PC, so I cannot download anything onto it, HP Compaq TC4400 with Windows XP Tablet PC Edition, Service Pack 3. Thanks in advance to any help I can receive.Disconnect the drive... Thanks to Computer Commando for trying to help, but Registry Editor and all MMC snap-ins are restricted by group policy. I can bypass this by doing a "jailbreak" of sorts, but I would not be able to save changes in the case that I did this.If the computer belongs to the school & you are not granted full access, there's nothing else you can do, other than contacting the school's IT department & let them deal with it.I believe it is a problem with the drive, it has occurred with every computer I have tried to connect it to.All Windows XP computers?Indeed. Should I try a different OS?I'm not sure, but the issue may be limited to WinXP & certain computers using it. I have seen the same error on a WinXP machine from time to time. Formatting of the USB device ALWAYS fixed it, but that is not practical in your case. http://support.microsoft.com/kb/330174 It would certainly be worth trying it on a computer with a different OS. Are the computers all laptops? Is the WD drive Notebok (2.5) or Desktop (3.5)? i.e. 2.5 drives are self powered, 3.5 drives have their own power supply. I have several WD USB notebook drives. 1 older used to exhibit the same behavior, been reformatted FAT32 a few times.I tried it on another computer running XP, had a little more luck. Was able to list folder contents for the drive, but then rendered unable to actually read anything, and after CLOSING Explorer Window, the computer had the CPU/memory usage shown below. I also tried it on a computer running Win7, got a warning that the drive needed to be formatted before being usable. Computer_Commando: http://www.wdc.com/en/products/products.aspx?id=440#tab3 - but it's a 300GB model. Another thing: Windows Delayed Write Failed to:
But at the same time: Disk Write Caching disabled for WD My Passport 070a Quote IMAGENAME PID CPU MEMNTFS file table is corrupted. Try chkdsk e: /f from the command prompt on the WD drive. If no success, there are other tools to try. |

Solve : Hardware Detect Reset w/o Post Diagnostic Card? |
|
Answer» Working on a project where I need to know when a system restarts. Cant use PING to watch for when the connection disappears and comes back since the project doesnt have another networked computer at the other end. The post diagnostic card sold here has an LED that shows when the hardware reset happens by sensing the Reset Signal: LED to monitor the Reset signal from: http://www.millennium-solutions.co.uk/diagnostic-tool-pc-computer/post-probe-code-reader-card.html If this reset signal is the internal reset signal and not the front panel reset status, I could use this to drive a 4N25 optoisolator to know when the reset signal is sent, but was wondering if ANYONE knew is there was an easier way than tapping into this post diagnostic card for sensing the reset signal. Best methods of interface are USB, Serial, Parallel to interface with the project I have. TRYING to be simplistic and keep costs down. This post diagnostic card would work, but checking to see if there is a better method. Another idea I had was to drive a relay off of USB or Serial and so when the service ends during a system reboot or shut down, the relay opens until the system boots back up and service starts back up to close the relay contacts. And then enable interfacing with my project. This may be the best method, but figured I'd run it past you all. Most simplistic idea ... Not sure if reset can be sensed thru USB, Serial, or Parallel if a system is given restart command. Haven't connected my multimeter to my 5V on USB and Serial to see if the power resets during the reboot cycle or if it holds steady thru reboot. If it does cycle the 5V out to these ports, thats awesome and the easiest vs having to run a software service to drive a relay. ThanksGuess I am going to go with the option of relay driven by service thru USB. Tested USB port during reboot and 5VDC doesnt cycle. Also looked at pins 2 and 3 with scope for D- and D+ usb communications and nothing there helpful to pin point a warm reboot condition such as a communication flatline vs timed com bursts. I was HOPING it would be that easy given that my thumb drives always BLACK out and come back on during reboots, but I guess thats just because their service was terminated during the reboot. Going to close this request for assistance and go with the relay enabled via service to know when the system reboots and comes back online. Quote from: nixie on November 04, 2011, 04:38:36 PM Working on a project where I need to know when a system restarts....Front Panel Reset is not a status, it's a control. I think it pulls the cpu reset line low. I would stay away from the USB, Serial, or Parallel because the OS has too much control over them. You want to be at the hardware level. Get a copy of the PCIbus specification & study it. http://www.dzjsw.com/shu/bz35.pdf You may find that it's not as simple as you think. RST# is not a status. It is asserted or deasserted by the card. The Bus provides no useful signals, it only DEFINES the signals & how they are used. The cards do everything & must conform to the spec to function without interfering with each other. In the long run, it will be cheaper to find an existing card & use it. Not sure if the one you selected will work. It's not clear if it locks the bus after completing it's routine. |
