NEW BUILD NOT POSTING, PLEASE HELP IT'S FOR MY MOM

[JacksonV]

I just put together a new build (not my first, I built it for my mom) and its not posting

Specs-

-Gigabyte Z370 Aorus Gaming 7

-i7 8700k

-16GB Corsair Vengeance 3200 mhz (tested in another computer and both working fine) (in the pics I gave Gskill 16gb 3200mhz which also was not the problem)

-Corsair h100i v2

-Corsair 750 watt psu (does work)

-Gigabyte AORUS GeForce GTX 1060 6G REV 2.0

 

What happens is I switch on the psu and the mobo flashes it's rbg lights for less than a second then everything turns off and the red power button (I believe also the cpu light) on the mobo stays on. When I try and press the power button the light on the cpu cooler comes on for less than a second and the fans twitch but nothing stays on.

 

I've tried-

-breadboarding with only the cpu/cpu cooler/1 stick of ram

-all of the cables are working

 

I've attached images below

Probably between CPU or mobo at this point. Similar thing happened to me for last gen (z270) mobos tend to break cpus and not the other way around so get a new mobo and put the chip in to see if it's the chip, vice versa, etc, and rma the broken parts

Tried a different PSU with the computer outside the case?

 

Sounds like a short.
