Screensaver not working

My screensavers have just stopped working. The cursor shows like its about to go to the screensaver and then just stops. Can someone please tell me why this is doing this? A suggestion on how to fix the problem? Please.

Have you just got a wireless mouse ? Installed/uninstalled any programs recently like Power DVD.If nothing else works,system restore could be a final option.

Do yourself and your Box a favour. Turn of all Screensavers. TSR"s like these, are a waste of good Memory and they can cause so many problems for other programs and Processes. Especially if you forget to turn them off to install most programs.You do not need them.
You can set your Monitor to Sleep without them, and require a password to wake up if security is an issue.
Just go to the Power icon in Control Panel.

its a problem with windows. if you have a wireless mouse or something like that the screen saver will not work. search microsoft, i believe they have a patch for it.
