I can play FPS all night without any crash but playing strategy games is hit and miss. Sometimes the computer would restart, sometimes it would jump back to window. All my hardware drivers are up to date, temp is normal and everything is still in stock form. I have lanparty ultra D, x800xl, 1 gig Cosair ram, Antec 350w psu and amd 3200+. Did anyone have similar experience with strategy games causing window to crash? btw, the game i played was Act of War.
