Hello. Since today i am unable to run any 3D applications. I tried several games and programs. It always crashes, starts do stutter and black screen and then crashes to desktop. I can play videos and flash fine. I have a TwinFrozr, running at 1350clock, 6500mem, 132power limit, auto fan speed, adaptive mode. I tried putting everything back to stock, downclocking and reinstalling drivers. Help please.
