I started having problems after I installed SP3 and I noticed in EVERY game I played, the screen would flicker, I know its not the screen because someone found a way to fix it in GTA IV and it works fine, Please help

(Running ATI Catalyst 8.12)
System Specs:
Intel Core2 E8500 @ 3.16ghz
MSI P45 Platinum Gamer Series Motherboard
Kingston HyperX 4GB DDR2 Ram @ 1066mhz
