Theoretically possuble, but i would say unlikely. The only way you are going to know for sure what is causing the issue is by cross testing compoennts. Put another GPU does it do teh same thing? Can you try your GPU in someone else computer?
Also what PSU do you have? I would also test the memory and operating system.
Its a 700 watt PSU, knew I forgot something.
I also checked my ram it seems fine, personally I don't think it couldnt be that considering if I pull the card it gets fixed, I don't even touch the ram.
My dad's PC recently had a problem itself (different/unrelated) but Ill see if he gets it back soon, ill test the card in that see how it goes.
A 700 watt what? Make/model
Whoops... I made a mistake its actually
CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
(Literally the name of it from Newegg)
Have you tried running in windowed mode to see if Windows produces an error? Most crashes are actually recorded, but sometimes you don't see the error because of conflicts with the renderer and Windows Aero configurations. Try running with the game in windowed mode. Another thing, have you looked at your Event Viewer to see if an application/software/hardware error has been posted there?
So last night it was getting a bit stormy here, so I decided to fully unplug the machine, Unplugged the PSU and then the surge protector, today I didn't have any issues when I powered it up. So I cannot test the windowed mode idea but I'll keep it plugged in tonight and try tommrow (Unless it decided to temporarily fix itself again), and honestly I don't know a whole lot about the event viewer, but looking at the process names and stuff... I don't see anything realted to nvida drivers.
