So I have the nzxt noctis 450 case with the gigabyte gaming z170-x motherboard, I built it over 3 months ago, no problems. Since about a week ago my power button has stopped working. I have the 2 large power connectors from the psu into the motherboard and the pwr switch and +_ p led things in.. What?? What's wrong. Sometimes I switch power off and on and for a brief second I can turn it on and it will power up. I also have a problem where when it actually does turn on the leds and PC itself boots for 2 seconds stops for 5 seconds then boots successfully. Thanks
