White Screen of Death

Hi there,
I recently bought the game. I played for about three hours with no problems, but then all of a sudden, mid scroll, the entire game just went white.
This happens now every time I open the game. I get the developer logos fine, but then I just get a big blank white screen that I can only close by alt-f4. If the game is windowed then the whole window is white, and everything else is fine. This hasn't happened to any other game I have installed.
I have tried verifying game cache, uninstalling and reinstalling, changing my monitor's refresh rate, and restarting the computer. None of this fix it.
Any advice would be greatly appreciated. Thanks
