check if your driver is really gone.
hmmmmmm
i checked the nVidia's website....
no driver for GeForce 4000 for windows vista! sad.....
but sometimes, windows xp's driver works totally fine too.
u can just try the old driver again.

(your video card is still working right? cuz looks like its pretty old)
