Quite frankly this AMAZES me!!!!

THis is how I did it on Win98/2nd. Edition...Click Add/Remove; reboot; go to Start (type in regedit); in RegEdit,click on HKEY_Local_Machine > find Software category; scroll down to NVIDIA Corporation; Delete the key (folder). Reboot. Follow the instructions per new drivers installation, then reboot... again.Make sure that you delete the old drivers folder; usually in the C:/ directory; also, go to C:/Windows/INF/Other. If there is an .inf file with Hercules, Guillemot, NVidia (example), remove it, before installing new drivers. NOTE: certain drivers do not place the .inf file in the INF/Other folder; therefore, the un-install utility might delete it, during the add/remove process.
