but sound like something has trashed the display drivers. try a system restore (if installed). if not, and you have a driver cd, insert it, go to device manager, open display adaptor, right click, properties, driver tab and click update diver. see if machine can find drivers.
I had this when I installed a new graphics card, installed but for some reason destroyed the VGA drivers. It would go into windows, but I couldnt see anything at all (but i could hear windows). Only solution I could see was to format and reinstall. Though keep looking for another option.
