My windows XP machine is very reluctant to shut-down. It will often get stuck on the "Windows is Shutting Down..." screen or a bit further on with just a blank screen, all the fans are still running and often the hard-drive too. I have to resort to a manual power-down. How can I diagnose what the problem is?
