When I go to turn my computer off. I click start. Click turn off computer, then it 'hangs' from anything like 5 mins upwards.
The processes tab in windows task manager is showing explorer .exe as going 03,00,03,00,03 etc.
Right click on 'My Computer' and select 'Manage' from the drop down menu, then check the System Log and the Application Log. This may shed some light on what is going on.
