Hello, and sorry for the delay- I was offline last night. Offhand this seems more common to a faulty Mainboard- rather than the power supply, since the mainboard provides the turn on command, and you get no response from the power button. Have any parts been replaced at this point? Also, have you tested any voltages from the power board yet, and do you have a meter?
