This is usually due to a newer operating system being installed on an older BIOS.

Try updating your BIOS.

Do you have any unknown devices listed in Device Manager?

Can you do the below


Right click Computer,
Properties,
Advanced tab,
Settings button (Starup and Recovery),
uncheck Automatically Restart.
Now when you shutdown see if it gives you an error message.

I know it sounds stupid, but...

In BIOS, disable Legacy USB Support.

If no joy, re-enable and disable AHCI.

If no joy, re-enable AHCI and ignore this post.

Did you try disabling the auto restart under advanced settings? If there is a problem with AHCI or other low level drivers then your system may error, appear to be shutdown and restart.

This done in BIOS (system setup). Check your motherboard manual for detailed instructions.
