Re: xp clean install
It's hard to make out in the pictures, but everything looks like the way it should be. DOn't see anything wrong with what you have. If you do want to uninstall the video software, you can do it in the control panel. Go to the Add/Remove program and uninstall the Nvidia display drivers. Your dekstop will go back to looking ugly again with low frame rates. You can also go into the Device Manager and uninstall the display adapter in there.
