Windows won't shut down at all. Everytime I try to shut down it starts to shut down and then goes back to the desktop. If I try to start a program it displays a message saying windows is shutting down but still goes back to the desktop and keeps on running. The only way to shut the computer off is to physically push the button on the front of the computer to turn off the power. When I restart it restarts in the right manner. Thanks for any suggestions on what to look for.
