Sometimes you'll see this happen to the OS (Windows) and/or drivers when there is a rapid or sudden shutdown and startup of the system. It usually take more that one time for this to happen, though once is enough.
Yes, two years ago I had to reinstall XP due to a sudden ( less than 1 second ! ) blackout.
Didn't know that a single driver could become corrupt, for the same reason, while the OS remains stable.
