I had to reinstall Windows 10 a few months ago and am currently on v1809. For whatever reason, I cannot shutdown my computer. Everytime I do, it restarts.
I'm sporting an Intel Core i7 4770K on a Z87 motherboard.
Typing shutdown /s in the command line only restarts Windows.
I didn't make any changes to my UEFI settings and made sure to install the latest drivers for my chipset, graphics card, etc.
I tried disabling Fast Boot, but that didn't work either.
I also don't have anything like LAN boot enabled in the UEFI settings and disabling the Network Adapter's "Allow this device to wake the computer" didn't help either:
Disabling Automatic Restart on a blue screen didn't work which tells me it's not an error:
Device Manager isn't showing any issues:
Looking at Event Viewer, there are three 10016 errors showing up after these system restarts. I'd read they're not important, but maybe they are:

The only other one that looks suspect is this USB driver warning:
The driver \Driver\WUDFRd failed to load for the device USB\VID_17E9&PID_02FF\U70T08100303.
I don't have hibernation enabled so Fast Startup isn't even a thing:
I also tried following the steps in this article but was unsuccessful: https://www.pcworld.com/article/247392/windows/my-computer-reboots-when-i-tell-it-to-shut-down.html
I'm starting to wonder if it's a hardware issue. Possibly something wired up wrong on the motherboard. I am able to forcibly shut down by holding the power button for 4 seconds so to me, that rules out hardware issues.
I didn't clear the CMOS yet, but I did reset the UEFI settings to no avail.
shutdown /r /t 0, you are telling the computer to restart. The/roption does that. If you want to actually shutdown, you want to use the/soption: shutdown | Microsoft Docs. Beyond that, it also may help to disable Fast Startup./s.
