I have a problem with my video card. The problem is that every time I play a game or benchmark my video card artifacts and crashes. It never did this before until yesterday. When I first played RoboHordes, after 10 mins or so it just locked up and crashed. Idle temps are: 46-48 Celsius and Load is 51-53 Celsius. I have however overclocked the card, but never had any issues until now.
