Nvidia Detonator
This will make darn certain all associated driver files for Nvidia cards are wipped and gone. I hope this helps you out.
my only gripe with detonator is it requires the .net framework to be installed. i'm not going to download a 23mb installation file to execute a file from a 33kb zip file. i'm sure it works well, but i doubt i'd use the .net framework enough to justify its download and installation.

also, ati has its driver problems too.
