I'd like to add that this could be either a graphics card or a monitor problem, nothing that has been said do far rules out the possibility.

I think that it's a problem with the graphics card. If the latest drivers give the problem even when reinstalled, try using drivers that are older, or beta drivers. Also try freshly installing the drivers (uninstall the current ones before putting new ones).

The issue might also be fixed by changing the settings of the game (resolution/textures/colours/frame limiter/etc).
