I have the ASUS 21.81a drivers that came with my GF3 Ti-500 card and I don't particularly think they are very good. I understand that I must uninstall them before installing the Detonators. I am familiar with upgrading on my Win98SE machine, but WinXP looks totally different. Can anyone give me a step-by-step guide on how to properly uninstall the ASUS's and then install the nVidia's. Thanks.
