PC Restarts on Shutdown

[AvengerShows]

When I try to turn my PC off (windows key , shut down) it shut's down and restarts it self . Does anyone know the solution?

Could be anything from issue with motherboard to ACPI setting not set correctly, hardware issue. Power supply not physically shutting itself off. How long as it been doing this?

First reinstall operating system, if does not do, then it is because of hardware.
