I keep my computer on at night sometimes (probably more than i should), and when I woke up this morning my monitor was off and my mouse and keyboard didn't seem to be activate. My computer is still running and sounds to be fine (no bios beeping as i've heard others mention). So far i've tried restarting the pc several times, and putting the RAM out and back in individually. Any clues as to what could be wrong?

A little update
My monitor does eventually recognize there is an hdmi output from my pc, but it's just a black screen. My keyboard also lights up after a minute or two, which is a weirdly long time for it to take.
