BleepingComputer.com: shutting down

I am still having problems trying to shut down windows and my computer.I do what I would normally do but screen stays and with no intension of closing down.I am having to switch of at plug which some say can damage the hard drive so I really need help.

You have something hanging the computer up at shutdown, whether it's a program, a corrupted file, a sound or whatever.

Go to start/run/msconfig and see what programs are running.

Had you installed anything new just before this problem started?

Hi a hung application prevents shutdown

If for some reason your computer wont turn off or a frozen application prevents you from shutting down in the normal ways-you can use the following procedure. be aware, however, that you won't get an opportunity to save open documents. Windows shuts down immediately-no WINDOWS IS SHUTTING DOWN or other messages. To performan emergency shutdown press Ctrl+Alt+Delete to display Task Manager. Open the Shut Down menu and hold down the Ctrl key as you click, Turn off. POOF.
