Thank you for that. I'm afraid she cannot run system restore as the computer starts with only a blank screen. She doesnt have an XP disc so the suspicion is that it would have been pre-installed. How would one try to format and start again from this situation - it in fact ot is possible at all?
does the pc have the Windows XP key sticker somewhere on the case? If so, you can format and reinstall XP from scratch using a borrowed XP disc as long as you enter the key from the pc case at the appropriate time
