Question PC Doesn't Restart or shutdown via Windows Power options ?

I recently assembled a PC with the help of a friend.
And I cannot get it to Shut down or Restart via the windows power options. Also can not get it out of sleep mode.

Here are the specs:
MSI MAG Z490 TOMAHAWK ATX LGA1200 Motherboard
Samsung 970 Evo 1 TB M.2-2280 NVME Solid State Drive
Kingston HyperX Fury 32 GB (2 x 16 GB) DDR4-2666 CL16 Memory
Corsair RMx (2018) 650 W 80+ Gold Certified Fully Modular ATX Power Supply



It does not restart with the windows power options.
It does not shutdown with the window power options.
When it sleeps it will not turn back on.
When I try to restart or shutdown, the power button and the rgb lights stay on on the PC, and the monitor gives a “no signal” before going into sleep mode.
Then to get it out of that state, I have to force shut it down via the pressing and holding the power button and then boot it back up.
Also, if there is a windows update It will not shutdown correctly for that procedure

It seems that it isn't shutting down properly, but somehow manages to shutdown the monitors.

It boots up fine when it is completely turned off.

What I have tried:
Turning off Fast startup.
Wiping the SSD with CMD. “diskpart” “list disk” “clean”
Did a complete uninstall of windows and a complete reinstall, 3 times.
Took the RAM, SSD, and the processor out and back in.

My workaround for now:
I must press and hold the power button on the PC to completely force shutdown it down. Then when I go to use it again, I have to boot it back but using the PC power button. Which is quite a pain given that I use it quite a bit.

Any help would be greatly appreciated.
I am new to this forum and I hope yous can help.

Refer to the Motherboard's User Manual to double-check that all components are correctly installed and configured.

Overall, my thought is that there is some physical misconfiguration with respect to cables.

Take a very close look at cables, connections, and pinouts.

Especially between case and motherboard.

Do you think it could be a PSU issue do you?

You said "Especially between case and motherboard",
But the only way to shut it down is to use the power button on the case.
Otherwise windows isn't able to shut it down completely. ( It will shut down the monitors and make them go into sleep mode but the power button lights and RGB stay on)

I have done all sorts of research and i haven't found anything close to this problem. So somthing phisical would make sense.
I'll do a triple check on all the components again.
