Windows 7: Monitor won't shut off

I unplugged my mouse and my Wacom tablet. Still no change.

Also, Windows Live Photo gallery screensaver will cause the monitor to stay on (just in case you're using that)

Not running it

There are more possible causes as I have dealt with this quite a bit. Let me know if it was the mouse. It normally is. You may have to get another one or set it so it can't send that signal...
could there be some power setting in the BIOS?

There are some sleep settings in most BIOSs. However I don't think that's your problem.

Did you try unplugging the mouse? Try a different mouse also. That may tell you.

It could also be a network sending packets preventing the monitor from turning off. If your monitor NEVER turns off there is something resetting the timer. You have to find out what it is. This is a frustrating problem.

If your monitor shuts off then turns back on seemingly randomly, it's probably your mouse or network. (or other input device)
