Diagnosing XP Shutdown Problem
I have an XP box which has just started to hang on shutdown. It seems to have started after installing a USB-2-VGA adapter. It won't shut down if it's unplugged either or in another USB port. I also have a friend who's experiencing the same problem and he has no USB devices plugged-in at shutdown. Both PC's will get to the power off stage and then just stop with the blue background staying visible. You can even hear the hard drives powering down.
Anyone know how to diagnose the cause and/or fix it?
