Computer doesn't want to wake up.
Ok, so here's the deal. whenever I leave my computer on and it goes idle and shuts the monitor off I can't turn it back on without a reboot. It will turn on if it only turned off a few minutes ago but after an hour or so it won't come back. Anybody have a clue as to what this might be?
