I've recently had problems with games installed on my computer and I suspect my graphics driver is faulty. For a few times when I play my games, everything is fine, but suddenly when I run it the graphics turn all black and white, with black of varying depth and pitch. Even with graphic options set to the lowest this still happens. This didn't happen for only one game but a few. I've updated the graphic drivers recently to no avail.
Help much appreciated, I'm using a ATI Radeon X1300 Graphics Card.
