Nothing happens when pressing power button

[QuackAFQuack]

Hi LLT.

I've acquired a new itx case and have swapped components around from a former ITX build to a new case (Evolv Shift Air).

Things I've swapped over from the former build is Mobo, RAM, CPU and GPU.
New things, PSU (Corsair SSF 750watt) and CPU cooler (Noctua L12s).

I had the build up and running managed to install windows 10 with just the basics connected.

Powered down and wanted to connect all fans / case connections and a different GPU.

Now I can't get any sign of life out of the system, tried swapping back to the previous GPU, the old system powersupply (corsair TX650m).

My guess is the mobo has died in the process somehow. I've yet to check if the Riser Cable for the GPU could be the reason but then FANs would at least start spinning right?

Cheers.

Yarp, already unplugged and replugged everything a couple of times.

Bench test the board and psu by themselves outside the case with only cpu installed

Try plugging out everything and holding down the power button a couple of seconds and replugging everything and try starting.

moved the mobo to the old case (SilverStone SG13) and plugged the old PSU. Having only the CPU and RAM on the board no life sign from pressing power button.

Take it out of the case and take the ram out. Short the switch pins instead of using a button

Nothing still.

Update: 

Still no responds from pressing or shorting the pins.
 

If I plug in a ethernet cable and get lights on the wlan port. Can this be an indicated the CPU has died somehow?
