Visit the Windows Update web site and make sure
to download all the available updates. I believe the

After using my computer 4 or 5 hours the screensaver stops working, I have
the logitech MX-700 wireless mouse but it does the same thing when I change
mice.. I can still make it work by using the preview button while in the
screensaver program. thanks Jim
