I have been having this really weird stability problem with my desktop. When ever I run Far Cry 2 with Windows 7 the game can run for 10-30 minutes then the system just shuts off. It's not overheating..atleast my censors tell me its not. Using HWmoniter and Catalyst to monitor the temps they seem within normal ranges...whats odder is I even can run GTA IV and stress the machine even more and the system will run it for hours... So I am 99% sure its my GPU...but then I get evidence of my GPU being pushed even harder with a different game and having no problems at all..Crysis/Warhead, GTA IV, TF2...all run fine..but Far Cry 2 does not. THe games that are capable of running in DX10 are, and are runnning at 1920x1080 resolution, usually with the settings maxed. Any ideas?
