Answer» This is on a Gateway DX4300, Phenom quad core, 8GB DDR2, Radeon HD 3200 (onboard), Windows 7 HM Prem x64... I tried running only 1 module at a time swapping all 4 modules into the primary slot with no joy.What does that mean? You can also try to remove all devices from the system, even the keyboard. This means removing the poser and data to both hard drive and DVD drive. Remove all USB things. The objective is to either get a beep of a BIOS logo on the display. Try just one stick of RAM. Swap RAM. Try power off/on cycle several times. You need to check the +3.3 , +5 and +12 volts on the motherboard. Quote from: Geek-9pm on June 11, 2012, 08:02:57 PM If the video was bad and everything else swords, the BIOS would make beeps. Well, that is what is expected.It worked until when it would not show the display at start-up. No beeps so far. Quote What does that mean?I mean swapping each stick of RAM into the 1st RAM slot closest to the processor. In my experience with different motherboards, that's the slot the manual says to use if only using 1 stick. Quote You can also try to remove all devices from the system, even the keyboard. This means removing the poser and data to both hard drive and DVD drive. Remove all USB things.Quote Where do I connect my DVOM meter leads? I can't find this info on the Gateway support site. I can never find very much usefull info on the Gateway support site. I can't even get the user guide to open with Adobe Reader UPDATE: I tried starting it with nothing connected (USB mouse and keyboard, SATA hard drive and optical drive, PCI-E cards ect.). I also swapped all 4 memory sticks into slot furthest from processor one at a time. Still the same result = no beeps, no display. At this point it is time to try another power supply Unit. (PSU) GOOGLE power supply pinouts OR look here: Google search for PSU pinouts Here is a general coverage of how to test a PSU. But if you find it too much, do not bother. It is more likely you motherboard has a problem. You can just beg nor borrow a PSU and see if that makes a DIFFERENCE. http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm Let's hope it is not the motherboard.Okay, I've checked the PSU with my DVOM and all voltages are correct. Next?One more thing. Plug in the keyboard. Turn on the power and watch the keyboard lights. At power on, all lights flash once together. At some point all lights will be off. Then at last the Numlock should come on. This is the clue that says the CPU is running and the BIOS found at least a small amount of usable memory. But if nit does not, your CPU either is not starting or there is no RAM available. To test the CPU, you put it into a known good mobo. That may no be easy. This is the limit of my experience. I gave up on repairing mobos years ago. I do believe a newer CPU have better warranties than its motherboard. So it would make not sense to buy a new CPU. The price of a good motherboard is a bit more that a CPU, but it varies. What I fear is that you need a new motherboard. But wait for another opinion. I am often wrong.

Quote To test the CPU, you put it into a known good mobo. That may no be easy.Not easy for me mainly since I don't have acess to a AM3 socket MOBO Quote This is the limit of my experience. I gave up on repairing mobos years ago. I can't seem to ever find where to order replacement parts from Gateway. I have experience building pc's and matching the components I need but not with selecting which MOBO from Newegg ect. would be correct as a replacement for a preassembled unit.BTW, I bought a new graphics card from Best Buy but nothing changed. I'm going to return it now. OK. Not the video chip. Don't give up. There are junk dealers out there that collect Gateway parts and recycle them. You want a real Gateway motherboard to preserve your investment in the CPU and the Windows 7 system. On a Gateway, use of another motherboard will make your Windows n7 not legal. (Not real sure of that.) Even Amazon has some junk recycle vendors http://www.amazon.com/NEW-GATEWAY-MOTHERBOARD-System-Board/dp/B005OAXMMO Keep searching and you might find that same Gateway motherboard somewhere. edit: found http://www.google.com/products/catalog?q=Gateway+DX4300+MOTHERBOARD&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&tbm=shop&cid=17830254347177186553&sa=X&ei=TAbYT_jpJ8TM2AX1iMmKDw&ved=0CI8BEPMCMAEOkay, I bought the second board listed in your link since the first only had 1 seller rating. I left out a bit of info in my first post of this thread which is the complete model # of my machine which is DX4300-15e. The board I bought on ebay says it's for a DX4300-03, But the only difference I see in the specs is the graphics card and the WiFi on the -15e. I hope I didn't make a mistake ordering this one. I couldn't find a board for a DX4300-15e anywhere. I need this QUICK so I paid $35 shipping overnight air. So I'll post again in a day or 2 after I get it installed, hopefully with good news. Thanks to you for your help Geek-9pm. Let's hope I did not led you astray. I think I made a mistake. I think the board I have has an AM3 socket and the board I ordered has AM2+. So my CPU will not fit into the DX4300-03 board correct? Quote from: lectrocrew on June 13, 2012, 10:52:20 PM I think I made a mistake. I think the board I have has an AM3 socket and the board I ordered has AM2+. So my CPU will not fit into the DX4300-03 board correct? Phenom X4 9750 specs Phenom II X4 specs DX4300-03 specs with Phenom X4 DX4300-15e specs with Phenom II X4 Quote from: Geek-9pm on June 13, 2012, 10:40:29 PM Let's hope I did not led you astray.It's my fault for not posting the complete model number. I sent a message to the seller to hold the order and asked what he had in stock as a 'next best' option for me. We'll see what he say's tommorrow and go from there. Thanks again! Quote Socket AM2+ is a CPU socket, which is the immediate successor to Socket AM2 that is used by several AMD processors such as Athlon 64 X2. Socket AM2+ is a mid-migration from Socket AM2 to Socket AM3 and both AM2+ and AM2 socket CPUs and motherboards have the potential to operate together. Actual interoperability depends upon other factors, especially the availability of compatible BIOS software, and some PC retailers, such as Dell, have not provided compatible BIOS versions that allow use of socket AM2+ CPUs on their products utilizing socket AM2 motherboards, such as the Inspiron 53So Wikipedia says don't blame AMD. http://en.wikipedia.org/wiki/Socket_AM2%2B |
