I put my computer to sleep last night before bed (a mistake, idk what I was thinking) and now it won't power on. I've had it happen before, but was able to hold the power button to reset it. This time though the power button doesn't do anything. I unplugged the power (from psu, not mb) but the motherboard LED is still on from residual power. I can't drain it by starting because as i've said it won't respond. It's been unplugged for over 2 hours so waiting seems like it could take a very long time. I tried pushing/holding the little power and reset buttons that are build into the motherboard itself, but they won't do anything either. I think it would start after it finally loses all power, but I don't know how to drain it.

I haven't made any hardware changes or opened it up in months, but I did do my windows 10 upgrade yesterday. It went smoothly and everything was working properly all night until I tried to wake it from sleep. I guess maybe I thought 10 would have fixed the sleep bug, but why would they do that when they could just introduce a stupid new photo app?
 

Don't know what ya tried. Just trying to help. Which OS?

TbStoy I said windows 10 in the op.

Mb: Asus p8z77-v deluxe
CPU: I7-3770k
PSU: Rosewood Lightning (1000 im pretty sure)

26 hours since unplug and the MB LED still going strong. I want to try disconnecting the psu to drain it, but idk if that will mess anything up or zap me so I'll just wait for answers for now.
 
Unplugged my psu from mb and did a paper clip test and turns out it's dead. While that sucks because I have to undo/redo all my cable management to pull it out and don't know if it's still under warranty, at least it's not a dead MB.

The CPU LED went off when I unplugged an hdmi connected to a GPU. I have no clue how that would give power to the MB, but that's what caused me to suspect it wasn't the psu. Hopefully that's the only problem.
