 i know all about beep codes its not one of them ive never had this happen on any of my PC'S before can anyone give me a clue as to whats going on.

Use a tester that has a load.  Plugging in a power supply without a load will not work.

the power supply is connected to the motherboard and when start button is pushed nothing works only the quiet beep coming from it
