I installed Windows 8.1 the other night. Been playing Dragon Age all day yesterday no problem. I put my computer to sleep for the night. I wake up and press a button on the keyboard. The keyboard lights up for a quick second but nothing else. Tried pressing power button but nothing. Holding it did nothing either. Tried the unplug and hold for 30 seconds and still did not work. My motherboard lights up and everything but when I press START, Reset, or clean Cmos on the motherboard itself still no response.
