HELP: nVIDIA GeForce FX Go5100

Hello guys,
I really need your help in this. Heres my problem:
I need to update my display driver in order to run certain programs correctly. I've downloaded many drivers off the nVIDIA website that were supposed to support my graphic card, but none of them worked. I've even called Toshiba (as my laptop manufacturer) and nVIDIA itself but none of them could help me. Everytime I try to install a driver that supposed to be compatible with the graphic card, during installation an error pops up and it says that it's not compatible with my graphic card. I'm very desperate to update the driver. When I try to play Counter-Strike:Source, after several minutes, suddenly the Blue Screen Of Death appears and the windows crashes. Is there any way I could update the driver? I'm begging you guys for help!
btw: I have TOSHIBA P15-S409 with Windows XP/SP2 installed.

I've successfully updated the drive and thanks to jutthope21 on MVKTech Forums was the only one that was able to help me out with this. He is the MAN!
