Question Extremely Stumping Question! Whose got what it takes to solve it!

Okay. So I am running into a major stalemate here hope you guys can solve it.

I try to power on my PC. Nothing happens, No signs of life.

Disconnect PSU and hook up to my other PC. Fires it up just fine no problems.
Reconnect PSU etc. etc. Still no fire.
Take a screw driver to connect positive/negative wire on Motherboard for Power Switch. Still nothing happens.
Replaced: Motherboard. CPU. RAM.
Did Not replace: PSU. Hard Drive. GPU.

Is it really that plausible that my old motherboard and my brand new motherboard are both bad?!?!

I was always told if the power switch is bad, using a screw driver to jump the connection would work. It didn't do anything. But the PSU works fine.

Why is my MOBO not getting power I'm so lost. I can wire it all up to my other PC same wires and all and it works just fine.

Is there something on the case I'm missing?!?!

Specs? Including monitor and video cable used.

Could be graphics card, video cable, video cable in the wrong video port or the motherboard doesn't support the processor (bios revision).

Don't know specs yet so those are my guess.

I’ve even seen faulty CPUs cause this problem

Basically any shorted component can do this. You must remove parts one by one and see when the fans start spinning.

Can we wait to see specs first. For all we know it could be an intel 8/9th gen installed on a 100/200 series chipset motherboard or 2nd gen Ryzen on 300 series mobo.
