BF2S Forums Video Card problems

I currently have
AMD 2500+
1GB Ram
WinXP Pro
Nvidia 6600GT Video 128MB
DirX 9.0C


When I fight on Karkand and a few other various maps
the rendering of the ground is green. All I can see is green triangles.
I don't know if it is a nvidia driver, game prob, or DX prob
This just started about a week ago. since then it has gotten worse.
if you get partially his with anything and usually see a blur, all I see is a green screen.
that eventually fades back into playing screen.

Anyone else having any probs.

Thanks
Matt
