BleepingComputer.com: Screen Flickers for some Games

This problem has been plaguing my recent games for reasons unknown. When I load said games, they flicker rapidly between a black screen and the game itself, hurting my eyes and making it unplayable. Here's the odd thing though, It can run games like Battlefield 2 and Half Life 2 just fine, but it always flickers with games like Angry Birds or Worms Reloaded or other non-demanding games. What's going on?!
