I believe its called scanreg /restore
However, go into DM in safe mode and check for any duplicates. If you have all driver info and know your way around windows, remove the PCI bus and restart. It will redetect all the hardware in case there is a conflict. Actually, first thing to try is go to safe mode and change your video display to 'standard PCI graphics adapter - VGA', doesn't matter if its AGP or not... its a generic safe driver. Restart. If it comes up into normal mode, granted with crappy display, then its the video card and just download/install new drivers.
