Receive absolutely no response from power button. Power led at power supply green, amber led on motherboard is also on. Have physically disconnected power and reconnected, to no avail. Do LEDs indicate that the problem is not the power supply?
Could it be as simple as the power button itself?
 
Solution
You can try jumping the motherboard pins to turn on. Lookup in the manual what two pins on the motherboard to use. It will be the two that have wires connected to the power button at the front.
