2 bad GPUs or bad mobo?

Rig is in sig and I've been having a heck of a time with my PC. I'm running Windows 7 Ultimate 64 I started experiencing artifacts while gaming followed up with bsods referencing the nvidia card in the bsod. I thought it was due to drivers and/or software I was running so I uninstalled some codecs and the problem seemed to have gotten better but not gone completely. I decided to reinstall windows and now the issue is worse. I did do some troubleshooting after the clean install cuz the problem was still there and the driver I had installed was the same as the one I was running before the reinstall. I get artifacts even in the bios now. At this point it has to be the mobo as I've tried each of my cards by themselves and get the same issue. Maybe the pci slot has gotten loose and worn after carrying the weight of this monstrocity of a Gpu over the years. Anyway, does anyone feel that it might not be the mobo? Unfortunatly the spare power supply I have have laying around has the smaller mobo power connector so I can't try a new PSU.
 
Motherboards based on the Nvidia 680/780-series chipsets are notoriously unstable. It's more than likely that the board is bad.

Are you willing to go with an Intel P35/P45-based board? (Chances are that you'll be better off trying to find a used board.)
 
I was planning on a full upgrade here in the next few weeks so the timing is both good and bad. Bad cuz I have no pc at all til I upgrade. I will prolly upgrade to a 920 so I'm assuming that I couldn't use my existing memory. Not like I want to as I had memory errors but could the mem errors be mobo related as well? I need to get
my newegg list going.
 
If/When you get your NewEgg list going, post it here. To save yourself some time, perform an in-forum search for "i7 920" for some build lists that were recently posted.

If you've had memory errors in the past, and you're reusing that memory, it could play a factor in your current ailment. But the Nvidia Socket 775 boards have a long history of stability issues.
 
I just reached out to evga support with the hope of rma'ing the mobo if I could. Still plan on building new pc but will use existing pc as server.
 
EVGA suggested I pop my GPU's into another machine. Luckily I had built the same PC for my brother-in-law and he was running the same mobo. I popped the first card in his PC and booted up and guess what...corrupted image. Same for the 2nd card. So it doesn't look like the motherboard is the issue and I'm really effin suprised that both GPU's wound up being bad. What kinda shit luck do I have? These cards always made a loud hissing/eeeeeee sound whenever I had a program running that was really taxing them optimally so who knows. Could the mobo break my GPUs? I know the PSU is suspect now but I haven't had any issues with my proc. I guess I've had shit luck with memory but I'm not running a crap CPU. It's a PC Power and Cooling and I paid a good chunk a change for years ago. How would I go about testing the voltage coming out of the PSU to see if it's too high or what? EVGA support was asking if I could note the voltages going to the GPU from the BIOS but I dont recall seeing that. If anyone can maybe give me some tips on how to test the voltage that are powering the GPU's that would be great.
 
I know how to use a multimeter but which pins should I be prodding and poking at on the GPU power connectors? Anywhere else I should take readings? Maybe going to the mobo itself?

Read the link: You don't need to measure from the GPU power connector.
 
Thanks, I had to read the article a couple times. I guess I skimmed over the important parts :) Time to bust out the multimeter. Thanks for the info dude.
