Shutdown problems can be caused by a multitude of different things, from a corrupted registry, corrupted device drivers, hardware problems, I've a couple of clients that had bad power supplies that wouldn't shut down.
Try doing a web search for "windows shutdown problems" to get ideas to troubleshoot with
