Computer won't turn on at all

test psu, unplug motherboard power 20/24 pin connector, use a paper clip wrapped in electrical tape (5 volts) to jump green wire and a black wire this should turn on the psu, if it doesn't come on it's dead, if it does you can use a voltmeter to test power.. this is not for pre p4 dell comptuers they use a proprietary connector

Connect the negative probe on the multimeter (black) to any ground wired pin and connect the positive probe (red) to the first power line you want to test. The 24 pin main power connector has +3.3 VDC, +5 VDC, -5 VDC (optional), +12 VDC, and -12 VDC lines across multiple pins.

I recommend testing every pin on the 24 pin connector that carries a voltage. This will confirm that each line is supplying the proper voltage and that each pin is properly terminated.

don't forget to reset the cmos when you reconnect the power, there is a clear cmos jumper on almost all desktops, it will be a jumper on 2 pins with one open pin, just move jumper to open pin +middle pin then back.

if comp still doesn't come on, could be cpu or mb
 
I tried using the paper clip method. It does not work. I had to try multiple lines because it does not tell me which one is green... they're all black. But anyhow, it doesn't work. Fans don't spin.

Plus, flame came out from the side.. like magically just came through the wall like how you ignore a lighter
 
all black wires? I don't think I've ever seen that, I've been repairing/building computers 30 years.. Is it a cookie cutter computer like dell or hp? some of them have proprietary PSU's. if it's a industry standard psu they are not expensive, just stick with the brand names, I personally like cooler master and corsair. Check your mobo manual to make sure of PSU requirements

You can see what my parts are below in my signature... XFX "Black" edition. All the wires for ATX are coated with black. I had to read the motherboard manual to see which line is for "power" then connected it with a random 5v line. But no luck. my fan doesn't spin. I'm gonna return it anyhow, thanks for your help :D
