WON'T POWER ON

[PCal2]

All in One Desktop won't power on. Have tried the following steps:

Unplugged power source and drained power, then held power button until light on front came on, but light goes out when I release button. There is no sound at all. LED light over power cord outlet is on demonstrating that motherboard recognizes adequate power source?
