Please help, this problem has happened from build 5600, 5728, 5744. I am currently running 5744. When ever I play a game, at random times it seems, my entire computer will freeze for about 30 seconds, then my keyboard will start working, followed shortly by sound. About 10-15 seconds after video returns, I lagg for a few seconds as it catches up, then it goes normal again. After I quit the game, there is a little popup saying Display driver nvlddmkm stopped responding and has successfully recovered. PLease, help me stop this!
