in the past week I have noticed that wial im playing battlefield 2142, the game will freez. Some times it comes out of it and others I need to hard boot the computer. It sems to happen more when Im in a vehicle for some reason. I had my 7900GS overclocked slightly but ive since declocked it though its still at 1.35v It was running great for a wail and all of the sudden. Ive since switched mother boards, switched ram, reinstaled windows i dont know what else to do. perhaps reflash the bios on the video card? what could it be?
