PC does not turn off automatically

I have just reformatted my HD and reinstalled XP but when I shut down the PC does not turn off automatically. Can you please tell me what I need to do so that it does shut off.

Also, Outlook Express shows a preview pane of each email and I would like to know how to turn off the preview.

Thank you for your help.

Roscoe.

Outlook Express > View > Layout > Preview Pane

As to shutdown see if anything here helps:
