NVISION: new driver for geForce Go 7900 gs? - NVISION

I've been having video problems with my laptop. It has the geForce Go 7900 gs video card. There was a video update a while back which I installed. However, every now and the the driver would crash and I'd get the message that "the video has recovered from a driver failure." Recently my system updated to Vista (Sp2) and I began getting pink outlines on sidebar gadgets. A web search revealed that it was driver problems and transparency. I rolled back the driver and the pink went away. However the other video glitches that surfaced now and then returned. I tried downloading a driver and inf from this site but the install said "no compatible video found". Any suggestions and/or links to a correct download would be appreciated.
