Setup

Asus Prime Z370-A
intel core i5-8600, 3.1GHZ
GeForce GTX 970
G.Skill Trident Z RGB 16GB Kit DDR4 2400MHz RAM
Coolermaster ML240L RGB
Coolermaster silent pro 1000w


When I attempt to boot there is no display and the keyboard doesn’t light up! On the motherboard the DRAM light is a solid yellow.


Things i have already tried

tried a variety of RAM slot combinations, both with a single stick and multiple.

Tried using the hdmi and vga port on video card and motherboard

Tried video card in slot 2

Tried it with video card removed

Tested monitor with another device

Rest CMOS and removed motherboard battery

CPU Socket Pins look fine

Tried the MemOK button (DRAM light flashed for a little bit then returns to a solid yellow)



Can anyone suggest anything els to try or can someone see a compatibility problem i might have

Thanks

It is a new build

Power supply was taken from a old pc and worked fine, i have also tried reseating the cpu!

How would I check the cooler isn’t shorting the cpu?

I have managed to get it to boot into the bios by putting the ram in A1 and A2

But everytime i try to navigate through the bios or change the settings it freezes
