Question [Closed] PC won't stay shutdown and keep booting up

[THLPH]

Background: I had my PC open for a few days to upgrade the CPU cooler fan and add a StarTech PCIE USB c card. And connected a new Motu M4 audio interface and installed their driver. It was working perfectly normal thus far.

Spec: Windows 11, 7950x3D, 7900XTX Nitro+, Team Group T-Create 64gb 6400MHz, NZXT N7 B650E mobo, Lian Li Edge 1000w Platinum, 2 1tb SN880X

Problem: Whenever I shutdown using windows menu or the front panel power button, as soon as all the lights turn off (which is only the GPU) and it clicks (normal so far). As soon as the shutdown click clicks, it immedietly click again as if I just click the power button, and every boot and starts. It also does it when hibernate. I set it to Hibernate on 1 minute and as soon as it auto hibernate and click, it immedietly turn on again. The only way to turn it off is to hold power button to shutdown or turn PSU switch off.

At this point, I'm deperate to try anything and the only thing I can think of the changing the mobo or PSU

TroubleShoots, things I've tried:

+Software:

- sfc /scannow and all the dism.exe

- powercfg –lastwake shows 0

- Power plan, shutdown button as shutdown

- Uncheck all the internet and usb devices ability to wake the computer

- Uninstalled the driver for the StarTech card device

- Uninstalled Motu using Revo Uninstaller

- Boot in safe mode and shut down, so most likely not drivers issue?

- BIOS: turned off USB and PCIE wake up

- Downgrade BIOS from 3.15 to 2.08, what I was using for months

- Clicked the CMOS reset button

- Windows inplace upgrade fix

- Installed Linux Mint to the 2nd empty drive and boot from there, still persist so most likely not WIndows problem

+Hardware:

- Disconnect everything including ethernet and GPU, only using onboard.

- Disconnect front panels, the only thing connected to the mobo are the fans, the upgraded CPU fans are not connected. Only previous case fans are connected

- Checked all connections and ram are seated

- Only connect 1 mouse and 1 monitor

- Changed CMOS battery

- Plugged from power strip straight to wall and tried different outlets

See if there is a setting in BIOS for power loss state where you can select to power down or boot up again. I wasn't clear if you said you did that. I would have suggested to take off the power button/front panel connector but you covered that.

I just checked, that is set to off

Two things you could try:

- Disable fast boot in both the BIOS and the advanced options in the Windows power plan settings (while making sure the USB power state is disabled in the BIOS). In that way Windows will not keep anything powered on when shutting down.

-You could create a usb bootable drive with something like System Rescue and boot with it, and once booted then shut down from it.

If neither of the two suggestions above work then the problem is likely not with Windows and probably hardware related.

Thank you for the suggestion, I removed the window drive and boot with system rescue. It shutdown normally. The USB c card or the Audio Interface definitely did something to the Windows install.
Since I've tried everything and the Windows still seems broken, I'll just reinstall Windows.
Thank you.
