Do you have a really old GeForce/TNT vga card?

If yes, then don't bother with any driver release of nVidia after the ForceWare v71.89 set.

As you can see from reading here, nVidia has stopped support for the following GPU's:

TNT2
TNT2 Pro
TNT2 Ultra
TNT2 Model 64 (M64)
TNT2 Model 64 (M64) Pro
Vanta
Vanta LT
GeForce 256
GeForce DDR
GeForce2 GTS
GeForce2 Pro
GeForce2 Ti
GeForce2 Ultra
GeForce2 MX Integrated graphics
Quadro
Quadro2 Pro
Quadro2 EX

Your only option is to use the last drivers released for the above GPU's, ForceWare v71.89.

Thanks for the info, I have a box of about a dozen or more TNT2 Pro's and a six pack of the 64 pro versions. I'll keep the addy handy!
