Guys help me figure this one out. Im at my brother in laws house playing Borderlands. He has a I7-920 with a 5970. In borderlands after maybe 20 minutes of gameplay, his PC will look up. Its not a complete lock up he can alt tab out but sometimes it is a lock up. I have removed his drivers used drivesweeper and I still get the same result. He has been playing Crysis without issues. Ne1 have any sugestions to try? I also manually adjusted his fan speed to 50% to see if its a heating issue. Anyone else having issues playing Borderlands with a 5970? It's running in crossfire because we do see the ATI logo top right corner. Thanks for any input.
