Question of the Day: Which is the most hair-raising South African mountain pass you've driven?
Computer wont stay off

While you need to find a better solution, the PC's PSU might have its own on/off switch.
And genetic's suggestion should be the answer, otherwise a PCI setting somewhere in the BIOS, unlikely to be a BIOS USB setting as that would only be for onboard USB controllers.

Review your Bios power settings, disable wake on lan, soft of, standby state etc etc

Press sleep in Windows and unplug your keyboard and mouse before it shuts down, see if it stays off. If it does then check your bios for allow usb/keyboard wake and disable that.
So you have not tried to confirm, you're just assuming.

Also (Not sure if still a feature on modern motherboards) check your bios for PME Event Wake up, Windows 10 loves to enable that in my bios, same with AC Back Function, should be set to soft off.

Remove your case's power switch from the motherboard's header pins while the PC is on and shut down via Start menu to eliminate that your case's switch is not the problem.

I thought the same, but if the switch circuit was permanently closed it wouldn't shut down from the bios

True.
Try is anyway.
It can build up a capacitance of sorts, and only trigger later. This dry weather may contribute.
Make and model?

Try this command in cmd prompt:
shutdown -s -t 01
See if it switches off.
shutdown -s -t 01
See if it switches off.
Latest bios?
I had a similar problem with my laptop which would switch itself on right after hibernating or shutting it down. In my case the problem was caused by the Microsoft wireless mouse adapter which was allowed to wake the computer.
I found an article which suggested the following steps:
1) Install the card and then put the machine into sleep or hibernation mode. When it resumes, goto the next step.
2) Open the cmd window using admin privileges (start -> cmd -> right click -> run as administrator)
3) Run the following command which will show you which device caused the machine to wake up. I assume that at this point you should see the offending device name:
powercfg –lastwake
4) Next, run the following command which will show you a list of devices that are allowed to wake the pc up:
powercfg –devicequery wake_armed
5) Right click on the start menu -> Device manager - Locate each device from the list -> Click on the power management tab -> Uncheck 'Allow this device to wake the computer'.
6) Restart and see if it resolves your problem.

Are you sure it has not become sentient?
