New build does not work

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?

BIOS updated?

Take out gpu and reboot.


Take out ram, leave one ram stick in.

Reinstall O/S

Compress Air Can spray everything

look at all connectors if they are plugged in correctly

look at all connectors male and female to see if anything is wrong


make sure monitor is on

make sure monitor is working, power cable and data cable

change cables


power supply may be DOA

take a Digital multi meter and probe the main mobo connector

main cpu to psu connector may be DOA either on psu side, or DOA connector on mobo


check for bent cpu pins


cpu may be DOA


did you drop a conductive material, like a mini bolt or mini screw on the mobo and fried it

does the mobo or psu smell?


were you careful with ESD precautions?

did you work on a ESD safe mat?

were you wearing ESD strap, or did you just touch the case frame all the time.


are the mobo securement bolts installed properly

they maybe too big and shorted something - Hey always an option, it could happen


do all the capacitors look normal, inspect all the way around each one!

are there any black marks on the mobo


could you have dropped a conductive material into the psu through the fan


other then that, I dunno what else to type

When its cold out, and you've spent hours on the dirty dirty web (no porn, just surfing normally) and you are bored, cant go hard trolling on this site, yet bored of hard trolling on yahoo.

CPU Fan header plugged in the right spot? I've never used that mobo you've listed but i've seen ones before that just wont even post without the CPU fan plugged in


Otherwise, @Canada EH covered pretty much everything!
