billhedrick,
You need to put the old video card back into the system, insure it is bootable and useable in both XP and Ultimate Edition 2.x. After you have done this you will need to remove the ATI drivers completely from both XP and Ultimate Edition 2.x. Reboot once more to XP and it should be working of the "generic" Windows video driver - DO NOT alow windows to "find and install" any specific video drivers on the reboot - it may go into the "New Hardware Found" routine, and try to get the correct drivers. If so, just cancel the action untill you are back to the desktop.
Reboot into Ultimate Edition and make sure you remove the "Restricted Driver" for the ATI card, too.
I'm not sure if you will need to use
apt-get purge package-name (where
package-name is the actual full package name for the ATI driver) in Ultimate Edition to completely remove the restricted driver, but it would probably be a good idea, as this insures you remove the actual program but it's config files, too. The actual ATI filename can be found by looking in the
/var/cache/apt/archives/ folder for a filename similar to this:
nvidia-settings_180.25-0ubuntu1_amd64.deb but containing
ati in the name.
After you are sure the drivers are gone in XP and Ultimate Edition, then shutdown the PC, remove the ATI card, install the nVidia card, reboot to XP, install the nVidia drivers/software and reboot to verify it is working correctly. If all goes well with XP, then reboot into Ultimate Edition, check for any updates via Synaptic, or via command line (apt-get update), install any updates found, reboot once more, then use
System>Administration>Hardware Drivers to install the appropriate nVidia driver software (see screenshot below). You should end up with a working nVidia card in XP and Ultimate Edition.
Let us know if you encounter any difficulties, and myself or some other Mod/Admin will jump in and help get them resolved.
