I am facing some problems while shutting down. I have a P4 2.8 Ghz with 768 MB ram, D101Ggc motherboard. When I click on the shut down from the start menu, the computer hangs sometimes. After that, if I directly try to switch it off using my cabinet (APX), it shuts down, but gets stuck showing the message Windows is shutting down. I use Windows XP Professional Service Pack 2 with latest updates installed. Can some one please help me out with my problem ?
