Graphics or what??

[rpembert]

I have a prob with dw. I get graphical artifacts in the game. They are little green dots every where. When I try to look at anything in 3d, the game freezes. Stutters happon all the time.
Other games work fine except Kinghts of the old republic and Jedi academy.

Comp:
Nvidia 7600GT 256mb
AMD 4200x2
1.5 gigs of ram.

Let me know if you guys can help.

Thanks
