right updated pc which was still on 98 to 2000, all good but it wiped a display driver my motherboard needs,reinstalled off supplied cd and now it gets to the windows background with windows is starting up and it then reboots.Tried to boot in safe mode and uninstall but it says vga must be switched off to uninstall which i cant seem to do.

Ill format as nothing of importance on but if i go to format it says that something is running and it cant lock drive to format, any ideas??
