Computer doesn't turn off

[Guest]

In many occasions, when I want to turn Off the computer, it doesn't turn Off
when I go Start, Turn Off Computer. The same thing happen when I go Start,
and you have 3 choices; Stand By, Turn Off, Restart. The monitor looks like
it is Off but the computer is still running. If I want to turn it On, I must
use the reboot button because the On/Off button doesn't want to turn On the
computer. Its happen even though all the other users are Log Off.

Thanks for your help since I joined the windows XP Newsgroups.

The first thing to always do is determine that the machine is
virus/malware-free:
