PC Sometimes doesn't display on first boot

[Snookums]

Every now and then when I turn my PC on, usually every other day or so sometimes several times a day. My screen will not display and my keyboard and mouse won't light up. I always have to hard reset (hold off button) and restart sometimes I have to do it several times. Any idea what this could be?

Forgot about this thread sorry. My issue has been solved now as I have changed my board and CPU as well as a fresh install so sadly I can't help discover the issue as it could have been software or hardware.
