What operating system are you running?
Does the system hang when it tries to shut down? When? Even when trying to shut down right after booting (ie, before running any applications)? In safe mode?
If 98/98se, have you installed the shutdown patches available on
Windows Update?
How are you trying to shut down? Start>Shutdown or are you talking about using the power button on your computer?
Is there anything visible (applications, etc) in your task manager that may be causing the system to hang at shutdown?
Did this problem just start? If so, have you recently installed any hardware/software?
Have you defragged your hard drive recently?
