So every time u push on button u hear a short beep? there's a difference between restart and shutdown
restart= goes off then start itself
shutdown=goes off
is your system shutdown or restart itself? I suspect bad psu or bad ram.

Bad ram? Sometimes ram can go bad so try to remove them clean the contacts(make sure to touch ram on edge) then install them or if u have a working memory(ram) try to test it in your system. Another possibility is power supply, if u have another psu try it.
