I have had this computer for just over 3 years now, and it looks like one of my GPUs might be going bad.
It started while I was playing the Might & Magic: Heroes VI demo. My whole computer would lock up, and I would see yellow green pixels dotting the screen.
I thought this might be a bug with the beta, since it was getting seg fault crashes as well (gotta love that 0x0000005 memory access violation).
Just in case, I installed the newest drivers from nVidia.
This freeze happened a few more times, getting slightly worse in the graphical corruption, and finally it happened outside of the game, just browsing the internet.
I suspected that maybe the GPU was overheating or something, I knew that my fans were full of dust. I finally pulled em out and cleaned out the dust, I have some funny pictures I can show you of the huge dust clumps I cleaned out (using q-tips and a can of compressed air).
The other card was worse!
Nice and clean afterwards!
I put everything back together and the computer got stuck while booting, just on a black screen. I reset the computer. This time I got a blue screen. Yay! After it restarted the computer worked fine, so I started browsing the internet, installed EVGA precision to monitor temps, and decided to run Heroes 6 again. I got the messed up graphics and a frozen computer again! I restarted and the graphical corruption remained, though the computer was fully useable.
GPU temps were at a constant 60 degrees btw.
However the corruption got worse over time. I unplugged one of my gpus (actually only the fan I unplugged... oops!). A loud screech later I had only 1 GPU inside and I still had the corruption. I am going to sleep soon, but tomorrow I will switch em out and see if that fixes the problem.
Also, another form of corruption I noticed was gray boxes with random colored letters/numbers in them (if I remember correctly)
I have been playing other games recently, such as Star Wars: The Old Republic beta and I didn't have any issues, I wonder why it got messed up now
EVGA 780i mobo
2x Zotac 8800 GT AMP
Any advice would be great! I did a quick google search and didn't find anything useful.
