Hanging PC for start up

[hardware_guy]

I've had my pc for nearly a month and everything was good, but since Tuesday I've been having a problem. When i start the pc sometimes, the asus rog splash screen comes up and it just stays on there, u cant press delete, F2 or esc. I can only restart it with the button on my case or hard shut down it. If i have restarted it or hard shut down it, it boots up but a little bit slower than usual.

 

I have the Asus Z97 Ranger motherboard, with a 4690k, a gtx 770 and windows 8.1 pro

 

If anyone knows how to fix this, it would be greatly appreciated, thanks.

Unplug the power cord and hold down power button for 10-20 seconds, then try turning it on.

if i do that, will it permanently fix the problem, or will i need to keep doing it?

What exactly does it do? I'd like to know.

Basically resets the CMOS battery, which is like volatile memory

Oh, so it's like removing the CMOS battery for 10 minutes?
