I went to take a nap after playing a game on the computer but when I woke up it had no display and my mouse and keyboard weren't lit. I restarted the pc and it didn't beep. No display, but the fans are running.

I have tried unplugging my pc, flicking the button at the back, and holding the power button down for 30 seconds.

I'm running a i7 4790k cpu, gtx 970 gpu, 600w psu, and a gigabyte GA-H81-D3 motherboard.

What could be the problem?

Also, it's been doing this for the past couple months but it would boot back instantly..
