I had a problem with Diablo 2, since it was too old for my comp. In full screen, it had these odd fucking colors throughout the entire screen, and it was just all around screwed.Right click on the shortcut, go to Properties, Shortcut- Target- Add '-w' without the ' to the end.What is does is gives you a smaller screen to play by. It cleared up Diablo for me. Might work for you. There might be a space between the .exe and the -w. If neither of those work, I tried.

As I said it has to do with game unable to work right with the system, and just fucking up.

What you did here was shrink the revolution size of the window, which helped it, only if that work for all games. 

Funny story about CnC game it's self has a unofficial patch to fix the graphic bug on newer systems.
