Graphics card freezing

Hi Michael
I have a evga geforce gt220 video card with 1gb of ram
It runs everything else on the computer fine but in moi3d it is prone to freezing, the mouse will freeze then jump 2 cm or more as the next frame renders

It has no problem playing combat arms very smoothly and only plays up in moi

any ideas
thanks
