In simplicity, what happens is that the power switch on the front of the computer (has 2 wires) connects to the main board front panel connector.
Shorting (touching) the 2 wires together momentarily will send a signal to the board to have the power supply turn on.
This would be the same as testing the power supply and jumpering pin 14 and ground on the supply.
Working with power is very dangerous. If you are not trained in power and taking readings, DO NOT ATTEMPT.
You can buy a power supply tester that will test the supply.
Your problem can be :
1. Bad power supply
2. Power switch not plugged in to the front panel header on the board.
3. Bad main board.
