I've recently installed a gtx460 as a part of a custom-built computer. Everything was running well for about a week, but now the graphics card is malfunctioning every time I run the simplest of games. The graphics card gets hung up before the game initializes, and I'm stuck with a black screen. It started yesterday and without any actual cause (I hadn't changed anything, I just left the computer on for an hour, and then as I came back, no games worked). I've tried updating the drivers, and it hasn't worked. Would anyone have any idea?
all help appreciated,
