ok.

open it up.

disconnect the power supply to all the hard drives. (physically 
disconnect them, along with removing the ribbon cable from the 
motherboard)

push the power button.

does it chime?

listen *VERY* carefully.

is there a high pitch squealing sound coming from the power supply?

if so, then the capacitors in the power supply are on their last legs 
and you need a replacement power supply.
