I have rebuilt my new pc twice so far with the same results. I have an Asrock pro 4 z370 motherboard, an 8700k, a gigabyte 1080, a 650w supernova psu, and an h100i v2. When I turn on the psu and the case, the light for the cooler comes on, the case fans start spinning, and the gpu fans start spinning. I was looking for a debug code, but either the motherboard doesn't have it or it's not turning on. No motherboard lights are turning on, and the gpu doesn't have any leds that come on. Does anybody have an idea on what the problem could be?
