Graphics problems

I get to the login screen, type name and password then I get a grey black screen with some boxes and diagnol lines. If I move my cursor around the color turns gold. I have a Radeon 9700 card, 2.4g P4 with 512M ram and plenty of hard drive space. I've reinstalled, rebooted, tried different window sizes. I've had no problems with games like FarCry, and Half Life 2.

My drivers were last updated in January.

I'm at a loss, any help would be appreciated as I just got the preorder and was really hoping to play this weekend.

try the catalyst drivers from omegadrivers.net.
