MERGED QUESTION
Question from oreyes1222 : "Defective Power Button On Front Tower Of PC? Or Psu Is No Good?"

Hello Guys Long story short I had a computer from 3 years ago that I haven't used and I decided to bring it back to life by turning it on on and no luck. Nothing comes on when I press the power button. No lights no nothing. So I took the psu and tested it with the paper clip jumper technique for the 24 pin connector (One end on green and one on black) and the psu fan was turning and it looked like it was working, it was spinning. But just because it was spinning doesn't mean its working 100%, it may be faulty I don't know. I was just thinking of getting a new psu. The computers psu takes in 125v and gives out 300w output. So I tested the 24 pin connector with a multimeter. Black probe on green/ground and the red probe on other wires and the voltages came out to be really low in the 3.3V range only for some wires and some wires didn't get any volts only 0v (DC of course). Maybe the psu is no good im not sure. Any suggestions and help is appreciated thanks in return.

Have you tried shorting the two pins for your power button header? http://www.tomshardware.com/forum/284272-31-power-case-switch-button
What are the FULL specs of your PSU (Make/Model)?

Here is a photo I took of it .

I forgot to awnser your other question. I did use the screw driver and touched the 2 pins to complete the circuit, but no luck nothing turned on. Mabey im touching it wrong, but my pin has more than 2 pins and has one space with no pin. It is a Jfp1 pin. Thanks for helping

What is the make/model of your motherboard?

Look at page 20 of this document:

The diagram titled "10-1 pin front panel connector" will show you which pins are for the power button. Those are the ones to short to see if the system will power on (and the button itself is defective). Note: While not the exact same motherboard, it is the generic Asus version and the pin-outs for this connector will be common.
