My graphics keep on crashing when I play games, this has only started happening today. I'll play for a few minutes without a problem, then the screen will freeze and loads of strange coloured dots will fill the screen in a sort of "patchwork" effect.
I have the latest Forceware drivers, I reinstalled them anyway just to be sure. My CPU temps are around 45C, mobo 22C, and at the last time I crashed my 6600GT was at around 60C. This has happened in both World of Warcraft and Half Life 2 so it isn't a problem with a particular game. I also took the card out, cleared all the dust away (it wasn't that dusty anyway) and put it back in, but to no avail, it still happens.
Does anyone here have a clue as to what is causing this problem? Is it simply a case of my card starting to die? I really hope not, the card isn't that old, my old GF4ti lasted years before it croaked.
Edit, it kinda goes a little bit like this when it happens: http://img.photobucket.com/albums/v325/YeOldeMann/shot0000.jpg
