Normally what i did is we need to check few things.

DDR Ram (i will install to running CPU to make sure the ram is working)
Bootrom (Will swap with other same machine's bootrom)
Hardisk (connect to computer as external to make sure its detecting)
Main PCB Controller (Test with other same machine's Main PCB)
DC Controller (Test with other same machine's DC Controller)

Theres a case happen to me before. I took out the Main PCB and clean all the dust around including cleaning the small fan on right hand side of Main PCB. Its run after putting it back.

your system software may be corrupt, or your hard drive failing

I've done the test ... The main control board was troubled
thank you for the enlightenment
