I can put my computer in standby but after a few minutes the fans will start up and if I hit the keyboard it will fully start up. If I do nothing and try to restart the computer in several hours-I will hear the fans running but nothing will come up on the screen and I have to reboot. This is Win XP pro. A relatively new system nottoo junked up

Tnx

There's a simple answer to this.
DON'T use standby.

If you have finished using your computer then shut it down, standby is a waste of time and energy. It has never really worked properly since it was first introduced.

Here is a link for a blank screensaver, make a shortcut to your desktop for the screensaver and right click and go to properties, then in the sortcut box hit a Hotkey that you would like to start the screensaver - So whenever you hit your hotkey your scrren will go blank
