I would say it is a bios-problem...

BIOS is set to wake the PC up on some event... Usually a network card.

If it never actually turns off and just restarts every time, then I'd
suspect issues with the motherboard.

Pen provided the only useful answer. Well, you have instead decided
to shotgun. Keep replacing parts until something works. No sense
'working smarter'. You may as well keep buying parts until something
fails. Had you done Pen's recommendation (a 15 second task), then
either you knew what had failed OR had numbers so that others with
knowledge could have added useful facts. Since you still have no
numbers using a multimeter, then no one with knowledge can post a
useful reply. Just keep replacing parts until something works.

A wake on LAN setting is another possible cause of a computer starting
on its own. Disconnect the LAN cable, then do a shutdown. Does
the computer now remain off ?

One Wake On LAN (WOL) feature, is effectively Wake On Activity. Which
means, the computer awakes, as soon as there is any activity on the
LAN port. You can try examining the properties of the LAN device in
Windows, and see what WOL options are offered, and "disable" the feature
to see if it makes a difference.
