Blank Green Screen

I was playing earlier, and all of the sudden the whole screen turned this dark Greenish Blue color. So i exited the game, restarted, thinking it would go away and it didn't...It's still there and it's been there for over an hour. Anybody know what to do?

Did you try any other game? Try reinstalling your drivers etc... If it is consistent through all your games it may be your Gfx card.

I tried several other games and updated my drivers and they all worked fine, but guild wars was still green, so i did a system restore and everything works fine now.
