boot - PC reboots after trying to shutdown… sometimes

What I am about to describe happens only sometimes. I would say in about 10% of the cases.



I have a system with a dual boot, with Windows 10 and Ubuntu. And in both systems when I decide to shutdown the computer, everything works as expected and the system shuts down completely. But SOMETIMES after 2 seconds of the PC being off, it turns itself again, kinda like if the signal that was sent to the PC was not the shutdown but the reboot.



When I do "Suspend" in Ubuntu, it is even worse! The machine goes to suspend state, but then it tries to boot itself up and after 1 second it fails and shuts down again... and tries to reboot itself again! And the loop continues without end! I actually have to take off the power chord for half a minute if I want to be able to reboot my computer, when this happens.



If this is something that happens with both OS, then it cannot be a problem with the softwre in itself.




Why could this be happening?



My motherboard is an ASUS P7H55-M PRO. These are the specs.
