Thanks for the replies. It's kind of odd though. 2D games such as Baldur's gate run perfectly fine, but any 3D rendering causes massive display problems.
I'll try fiddling with resolutions and refresh rates to see if it helps any, but so far it hasn't.
Another thing that occurs is that when I start my computer, the Dell loading screen that comes up before the windows loading screen the colors are completely messed up. When it hits the windows loading screen the colors are back to normal.
I just bought a ati x1600 agp if that clarifies anything
