Enuff

I had a system just last week that had the same fault, I did a fresh install and all was ok, and still is.... the guy told me that his kids sometimes turn off the pc without doing the proper shutdown, I told him that will have caused the problem.

You can usually tell if its hardware or software causing the problem, I normally run Knoppix (Linux bootable cd) if it boots to the Linux desktop then 99% of the time its a XP fault and not hardware...
