If you open the back you will find the Y-sus to the right and the X-sys to the left. Unplug the power connector to the y-sys and see if the unit stays on, during the POST or Power On Self Test you should hear the power supply relay click on then moments later the system power on relay if the power supply is ok.

If you push the power on button and nothing happends no clicks from PS relay then you may have a Main system control borad failure.
