I've got the same problem: the game runs for 10, 15, 20 minutes, sometimes it runs for an hour. But sooner or later i get a black screen, the sound starts looping and the pc becomes unresponsive, so i have to do a hard reset. I've tried everything from lowering game settings to updating BIOS and nothing has worked for me so far.
I've checked temps and they're fine. Also, I run games like Metro: Last Light, Crysis 2 with no problems whatsoever, so I don't think it's a hardware problem.
If anyone has any kind of fix for similar issues, I'd be happy to hear.
