Right now, whenever I run a DX9-11 game, it just shutdowns my computer either after a few minutes loading or while loading. (Tried with Borderlands, ANNO2070, Kingdom of Amalur, Civ 5) It does not crash when I only surf on the net or play some flash games (ie. Dofus)
What I did without success:
I did a mem. test (MemTest86+) and found no errors.
I replaced my stock chipset fan with a 60mm one as I thought it was overheating. (bleep Intel mobo is hot)
Ran a stress test on my GPU without any problem.
Updated my DX drivers, VC++ redist
Updated my graphic card drivers
Tried another identical GPU, still crashes.
Ran a stress test on my CPU with Prime95: No problem.
So now I'm out of ideas.
