Uninstalling drivers under Windows XP has always presented me with the problem that my machine always re-installs the driver on reboot. I've never been able to cancel the process, so my successful experiences with my ti4400 have been when I installed the executable first. That creates a directory with all the necessary nVidia files unzipped and then attempts to change the driver. It will ask for a reboot. If you have problems with the driver's installation after rebooting, use Device Manager>Graphics>Upgrade Driver and point to the nVidia directory that was created, and reboot again. After you've done this, if you have any old nVidia directories you can delete them, but keep the new one.
Using this method I've never had to go the Device Manger>Graphics>Upgrade Driver options, but it is there just in case.
