Hi, I got a problem, my PC freezes while playing certain games. The screen freezes,the ctrl-alt-del doesnt work, only sound continues however I can hear only some ambient looping from game, not like game would be played and I could hear sounds from realtime play. This happens only on certain games like COD4, Farcry3, Bioshock infinite, but not on games like Half-life2, metro2033/last light, COD2(interesting since COD2 and COD4 has basically the same engine)...cod4 freezes always after +- 10 minutes, while farcry3 after 1-2 hours
I tryed to run stress tests on GPU, RAM, CPU (prime95 for 24 hours), I tryed to test my GPU on friends PC (runs perfectly)...I found it doesnt matter if the game runs on dx9 or dx11. Temperatures at max load are on normal level. Only hard reset can help.

You've got a pretty good system there which should be enough for games like that. I myself play COD4 Promod with a system which is not even closer to yours but never faced anything like this. I'd suggest you to re-install your windows and the games too if you haven't tried it yet.
