I upgraded from XP Home to XP Pro for the remote desktop feature. XP Pro did not recognize my Nvidia GeForce2 MX200 card and used a default adapter & driver. I could not get the current Nvidia driver to work and in my efforts I apparently disabled the VGA Adapter so now I have nothing on my screen. When I reboot the machine I see the initial data, like the memory test, but once windows initiates the screen goes black. I know how to enable the video adapter if I could see the appropriate places to click but obviously I can't. Help, PLEASE.
