Here's the situation. I have a Win 2k with SP2 installed. I had a Nvidia TNT2 M64 video card with 32 megs of RAM. I got an ola Viper 550 card and I needed to see whether it was working. I swapped the card and the Viper was working fine. When I put the TNT2 card back the Windows couldnt get passed the boot screen. It boots fine in VGA mode and when I uninstall the video drivers. I tried substituting generic monitor drivers and it didnt work either.
Please help me. I really do not want to reinstall the Windows.
