Yesterday I installed the Geforce 8600 GTS video card. Everything worked fine until today.

Yesterday I monitored the GPU temperature with the Nvidia monitor; and it averaged 60 to 70 degrees celsius.

I checked the mobos temperature in bios and it appears to average around 45 degrees celsius. This morning I installed PC Wizard 2008 to monitor the CPU Temperature. Right now it is 47 degrees celsius.

This morning while sitting the pc was sitting idle; the screen lost the video connection and went black. I did a hard shut down and rebooted the pc. Everything seems to be working; except the mouse is very DIFFICULT to control. It STICKS causing me to loose control of it, every few seconds.

I'm thinking about removing the Geforce card; and resetting the bios and go back to using the Geforce 6100 card. I'm not into video games, mostly just sort of experimenting getting to know my pc.

Also I don't think I have very good air flow inside my case.
In addition, though all the fans work; I don't think they are doing actually doing very much of anything to cool the inside.

The fan on the Geforce 8600 works but it looks kind of impudent.

When I put my hand over the exhaust on the back of the case, I don't feel any air moving. When I wet my hand, and held it over the same location I felt only a slight bit of air flow. Is this normal? I'm thinking of replacing this fan with something better. I'd appreciate any recommendation for a fan replacement here! Noise is not a serious issue for me.

This pc makes no sound; compared to my older pc; I can hear it from the next room. Also the two PSU fans are kind of wimpy when it comes to creating air flow.


Aditional INFO. Things I did earlier this week.
I had been worrying that I may have fried my mobo while installing an inexpensive 600watt Ultra psu.

The pc was down on Friday and Saturday as I went to purchase a new psu. I had already reset the bios. I then installed the new 520w corsair psu, with the 24 pin, and 4 pin 12v connectors; and the 8600 gts video card.

I started out using the whole 24 pin connector and the 4 pin 12v connector. I've seen, or read recommendations that one use all 24 connectors in the 24 pin slot. If I understand correctly, this is how one gets the 3rd 12v rail. I've also read the opposite in a few places; that using all 24 instead of just the 20 pin connect may create system instability. My original 300w power supply only had 20 of the 24 pins connected. The GPU temperature was averaging between 65 and 70 degrees celsius when I changed from the 24 pin connector back to 20 pins. The four on the left being empty. I don't know if this has anything to do with the GPU or not but after I restarted the pc the GPU began to average 55 degrees celsius. I don't know whether, that may be just coincidences.

I had already stopped worrying about updating the bios. Though I had updated the drivers for the on board card. I'm not sure if this was necessary. Turned out all I needed to do was make sure the new card was connected properly, for my gateway mother board to recognize it.

After installing the second new psu the pc would not start. So I removed the new card and restarted the pc; to my complete surprise it started properly. I then reinstalled the card properly and the mobo recognized it with no issues.

That was late Saturday; now I'm back to trouble shooting the video disconnect and blank monitor. An hour ago; I went to the store; leaving the pc on; when I returned just now the screen was black; and the green power light on the monitor was yellow. Again I did a hard shut down, and restarted the pc. The next time it does that Geforce 8600 gts video card is out of here.

this is just a side note.
I read some place where the Geforce 8600 (but not the EVGA Geforce 8600 GTS card as I have) was recommended to someone who had a similar system to mine. It was suggested the 8600 was the latest card which would fit into their machine. Since I have an almost identical machine; thats how I choose that particular video card.

Here are a few other incidentals.
1. When I installed the Geforce video card the directions say to first update the bios. I found several instances more experience people couldn't find any bios updates anywhere for this FIC mobo KTBC51G LF

2. The directions say to remove the existing graphics adapter by removing the retaining screws. Also to apply the retaining crews when installing the new card. I dont think there are any retaining screws; and I didn't remove the old card as I the mobo appeared to recognize the new card without the need to remove the old one.

Also during the software installation for the new card; I may have made an error when the program asked me something regarding my systems use of 32 bit or 64 bit. Thats not very clear but I don't remember the question exactly. Anyways I was a little confused as always; and choose the 32 bit option; perhaps I should have chosen the the 64 bit option. I don't know what the heck I'm talking about. Perhaps some one does; who knows?


Thanks for any, and all comments, HELP, and or attention to these issues.

wow, long post. ok, a few things to clear up...

I didn't remove the old card
you cannot physically remove an integrated video card for it is built into the motherboard, you can only disable it. this may be the root of your problem, did you disable your onboard video card in your BIOS? did you uninstall all of your onboard video card drivers as well? having a dedicated video card installed without first disabling the onboard video card and uninstalling all of its drivers is sure to cause system instability.

definitley sounds like you need new fans. i would recommend changing all your case fans, you will notice quite a drop in temperatures with aftermarket fans.

I'd appreciate any recommendation for a fan replacement here!
we need to know the size of the fans first before making any recommendations.

good, use the whole 24 pins. the only reason why the +4pins are seperate is so that the power supply is compatible with older 20 pin motherboards.

something regarding my systems use of 32 bit or 64 bit.
http://support.microsoft.com/default.aspx?scid=kb;en-us;827218. readup to find if your OS is 32 or 64 bit.Hello Homer; thanks for the reply.

Sorry about the long post. I was trying to be sure I covered everything.

I read the Microsoft article and apparently I do have the 32 bit version of windows. I knew that, or not; it gets confusing sometimes.

I also went into add remove programs and clicked on remove AVGA drivers. (It was the only reference video drivers in add /remove.) Then it gave me the option of removing only the Nvidia display drivers. Which I did. Then it asked if wanted to remove all Nvidia profiles. I wasn't sure about that, but I chose yes. Then I restart the pc.
Prior to that I went into the msconfig utility and start ups and unchecked Ncpl, and Nvmctray and ok without restarting.

Now the found new hardware wizard is on the desk top. I'm not sure why the monitor is working right now.

In device manager, right now, there is an entry for

Nvidia network bus enumerator
Below that under other devices there is
a ? next to, Video controller (VGA compatible).
I suppose all the Nvidia display drivers have been removed. I supose I just need to pop in the CD which came with the 8600 gts?

I forgot to mention the heat sink on the CPU looks like an aluiminum radiator, sort of.

My PC only has one fan (besides the ones on the psu) there is a label on the case fan which reads; AVC Model DSO9225R12HPFAF
and Hydraulic Berrings. It's dimensions are 3 5/8 X 3 5/8" X 7/8" deep.

I'll plug the the other 4 pin connector back in as you recommend.

I guess this post is getting a little long as well; sorry bout that.
Thanks again for the help; I'll post back with a follow up later on.

you will need those on, for your new card also uses those services. did you remember to disable your onboard video in your BIOS?

you might as well go to nvidia's website and download their latest drivers as opposed to installing their old drivers found on the CD.

i recommend the Scythe Kama 92mm fan then. does your case have the option for a front intake fan?Hello Homer,

Well hum, where to begin. Yes, the Bios well I started over from the beginning.

I went into the Advanced Bios Feature; and the fourth boot device was listed as (Nvidia Age) which I disabled. As of right now it is still disabled. I suppose I should leave it that way?

I then went into add remove and uninstalled the Nvidia monitor drivers again.

I down loaded Driver cleaner pro; went into safe mode; and disabled Panda Anti virus for the umpteenth time. I choose the "Nvidia option in Driver cleaner and it removed about 4 items.

I emptied the trash as recommended; restarted, downloaded, and installed the new drivers from EVGA's web site.

Also I went into config util's, and those start items I unchecked before; have been reactivated.

I think that's it. Everything appears to be working fine.

I'll probably get that fan you recommend in the next few days. I'll also go in and reset that four pin connector today.
The case doesn't appear to have a place for a fan at the front of the case.

In the front, there is a vent directly above the bay, where the hard drive sits (I think its the hard drive) and a large plastic shroud which directs air from the vent over top of the CPU's aluminum heatsink.


Thanks again Homer for all the help.Quote

was there no option in the BIOS labelled "onboard devices" or something along those lines? in there you should be able to enable/disable your onboard video device.

your welcome.

*added note*

if your temperatures are still high, dont be AFRAID to carve a few holes in your case to plant some fans, unless it voids your warranty...Hello Homer,
In answer to your question, no. I clicked on everything in Bios looking for any sign of video adapters. The one I disabled before called (Nvidia boot age) is the only reference I could find. I suppose I may have to reactivate that at some point.

I did discover there is an option in device manager; when I click on the Geforce 8600 gts entry under display adapters; to small icons pop up in the tool bar labeled "disable" and "uninstall"

I learned about that, and the following from an article at Tweakguides.com
I think there are half a dozen other ways to get to the device manager, to accomplish what the article describes.

"To view unused devices in Device Manager, do the following:

1. Open a Command Prompt by going to Start>Run and typing "cmd" (without quotes). Once the Command Prompt is open, type the following lines, pressing return after each:

Set devmgr_show_nonpresent_devices=1

Devmgmt.msc

2. In the Device Manager window that opens, go to the View menu, and select 'Show Hidden Devices' - this is very important if you want to see the unused devices. Now expand each of your devices and look through all the sub-components listed. You will see that some of the devices are shown in a lighter grey color..."

Anyway, I had about six monitors listed; I removed all but two, this one (plug and play monitor) and one other, which also had a greyed out monitor icon, listed as "default monitor".

I haven't found any sign, anywhere of the Geforce 6100.
There is room for a fan in the front. I'll have to think on it awhile before I start cutting holes in the case. I think I voided the warrenty on this pc, when I installed the psu, and video cards anyways.

Well tomorrows another day; and by the way, Happy new year!

Tmchappy new year to you too .
