mods please move this if this isn't in the right forum. my desktop pc monitor won't go to sleep. it started when i added the microsoft keyboard and mouse (wireless, i forgot the model). before this, my monitor would go to sleep after about 20 minutes, but now it never goes off. my dad looked at it and says what i think, something in the software of the keyboard and mouse is preventing the computer from going to sleep, and i would like to fix this so that my monitor would go off. thanks.
