I recently formated my laptop's hard-disk and reinstalled Windows XP Pro (to get rid of all my old garbage). Now unfortunatly when I click on the start menu and navigate to the "Turn Off Computer" button, the window that appears which should contain the Stand By, Turn Off and Restart buttons, contains all 3 buttons but the "Stand By" buttons is disabled

I feel stupid having to ask you guys how the fix this problem but I have tried all of the things I can think of to fix this problem and have failed.

Any help that you can provide in solving this problem will be greatly recieved

Yours Faithfully,
TTAYO
