Crashing in Graphics heavy games

[LateX'Dog]

Hey guys, just purchased and installed Battlefield 3 and randomly i get a screen lock with white squares across the screen.

This also happens in other games.

My system is:

Core i7 920 @ 4.2ghz Cooled using Noctua NH-D14 temps are 38c Idle and around 50-60c 100% load

2x 1gb GTX 460's overclocked to 800/1600/2100 using the 285.62 drivers. Temps rarely go above 75c

850w Corsair HX

Any ideas?

If it's squares, it suggests a faulty GPU, try testing each at full settings on their own.
