I have re-seated the GPU, CPU and RAM. I have been able to briefly see BIOS before it shut off twice.
It shuts after ~20 seconds

specs:
- NVIDIA 4070
-i7 13700k
- Asus prime z790-p WI-FI
- Seasonic AK500 deepcool CPU cooler

Having a full run down of your system specs would help a lot. We arent so great at reading crystal balls here at TPU. Gotta help us to help you.

If it shuts off instantly, like as soon as you push the button, you may have a short somewhere. I had a bad Molex that was driving a bunch of fans.. was tough to spot and took some time lol..

That motherboard is LGA 1200.
That doesn't work with a i7 13700K....
I wrote the wrong board lol. I know all the parts work with each other because I did the exact same build with my brother. This is human error. Updated the board

You have a "K" processor, so with an iGPU. As a troubleshooting step, take out your 4070, and attach the HDMI to your mobo.

I took out the gpu and it still shuts off

Just a note: all the lights and fans turn on while the pc is on

have you tried using a different power supply?
I haven’t, maybe I will try if nothing else works

Is it a new PC? RAM sticks at positions 2 & 4 (count starts from CPU socket)? Do you happen to have this motherboard speaker attached for error signals?

is the cooler properly installed?
Plastic foil removed, thermal paste, correct mounting kit used, properly tightened down?
what is the CPU temperature in bios?

Yes, I just built it haven’t got it to run. I put the ram in the slots from the motherboard manual (2 & 4). I didn’t plug in a motherboard speaker, don’t know how that works but I will look in to it.

I have reinstalled the cooler once, maybe there is something critical I have been missing. I will watch a video on the installation. The computer doesn’t boot in to bios 99% of the time. I have only seen bios briefly before the computer shuts off again

Try just 1 stick of RAM each at the time in all different slots.
I will do this
