I am completely stumped with this problem so I've decided to seek some advice from you guys.
Around a month ago I purchased a EVGA GTX 590, after installation on idle the computer would work fine, but during load (i.e. gaming or stress tests involving GPU) the computer would shut down, I isolated this problem to the generic PSU I had, and had it replaced with a Corsair HX850W.
After that, everything worked fine for about a week, and then artifacts began to appear in different games I played. I don't have any screen shots with me at the moment, but this video is a perfect example with the same problem I have.
Battlefield Bad Company 2 -
League of Legends -
And I also get similar artifacts in Eve Online.
Now the weird part comes when I tried to do stress test (not games) to see if it gives the same problem.
- I have tried Furmark, Unengine, 3dMark and all run fine with no artifacts.
- I have also tried memtest to see if it might be ram problem but it passes with over 32 hours of run time.
- I have also tried Prime95 and OCCT on my CPU and it passes fine with +15hours on each.
I have also tried multiple drivers, both official and beta from Nvidia, first with the driver sweeper + safe mode option, then with a fresh install each time (yes...fresh install just for driver -.-) but doesn't fix the problem.
So now I'm completely stumped on whats causing the problem. Listed are my computer specs below.

Corsair HX850W PSU
