Ok so when i play certain games this happens : The game freezes and eventually starts working again but all the graphics end up corrupt, if i alt tab out and then alt-tab back in the graphics go back to normal and i can continue playing the game.
Now i say certain games because it does only happen on certain games most notably on Red Alert 2, Dawn of War 2 and recently the Diablo 3 Beta. Older games like Act of War, Evil Genius, C&c Generals, Battle Realms and Battle for middle earth 2 don't have this problem. ( i will test more games )
It happens randomly and can happen 5 minutes in or 2 hours in and can be frequent, every 5 mins or not, every 40 mins. I get no error messages and the game works fine once i alt-tab back in until it does it again.
I've done memtest on my ram and it no errors, my gfx card core temp doesn't exceed 60c and all my drivers are up to date.
This is how my games end up looking :


Anyone got an idea?
