Operating System: Microsoft Windows 8.1 (64-bit)

I have HP Z420 Workstation. Yesterday I turned on PC. First few seconds everthing was normal.  All led , lights and FAN were working. But about 5 second later PC turned off. Led,  lights and FAN stopped.  5 second later PC turned on again. Later turned off. It is constantly turn on and off. I aparted all devices and then reinstated . Nothing changed.

 

Hard reset did not work. I researced on Internet. Somebody says it is about short circuit. But I couldn't find solve. Please help me. Can't I solve this problem without getting my computer to technical service?
