Ab350 Fatal1ty Itx. No post - Turns off

Hello,
this is my second motherboard as the first one come DOA.

My components:
AB350 Fatality Itx

Ryzen 1700X

GSkill  TridentZ F4-3000C15D-16GTZB

and

Corsair Dominator Platinum CMD16GX4M2B3000C15

Sapphire Radeon Rx Vega 56

Silverstone SX650G


I connected the PSU cables to the Motherboard and the CPU(EPS) plus connected PCIE to the GPU (blue cable).
I turn it on, then GPU and fan lights come one, PSU fan turns on and RAM (CORSAIR) light also turns on.

After a few seconds, I can hear the fan GPU fan speed up and down then everything turns off.
I connect GPU to monitor with HDMI, monitor doesn't say 'no signal' but also nothing shows up.

Fisrt I used the GSkill RAM:
I have tested without RAM and it beeps 3 times.
I have tested with one RAM in A1, no post and no beeps.
I have tested in RAM slot B1, no post and no beep.
I then tested with Corsair RAM: same thing

I take out the GPU, no beep.
I re-seat GPU and nothing happens.
I have already taken out the PSU and reconnected all the cables.

What am I doing wrong? do I need to get different RAM or is it my GPU?
Please help :(

Probably CPU power not fully seated... give it a good push in..

Hello,

I can use a 1800x from someone else to tested but I think it might be my GPU.

It's not sitting all the way in.

Case notch to acre the GPU doesn't let me push it all the way in. I can put some small standoffs.
