NVIDIA GeForce Go 7950 GTX

I had posted this earlier in another thread. Seems it was the wrong area, so will try here.
I am hoping someone here can help me. i have recently required an older model Alienware Area-51 m9750. It is running on Windows 7 32bit and everything is working excellent except for the graphics. From what i understand it has a NVIDIA GeForce Go 7950 GTX. I can not find a driver for this at all. Right now the device manager is showing a standard avg graphics. If I upgrade it then it does show a NVIDIA GeForce Go 7950 GTX but the screen will go black and then upon restarting the BSOD. Can anyone point me in the right direction?
