Step 3: Enough Talking, Let's Do It!

Before starting let me tell you that by following this guide you will void your power supply's warranty (that's why I said a preferably old PS), so if you are using a brand new one, please make sure you want to do this. What we have to do is actually quite simple (we also don't need to open the PS box), here are the steps to follow:

1) With the wire cutters, cut the GREEN cable coming from the power supply to the motherboard connector.

2) Cut one of the BLACK ground cables at the same height as you cut the green one.

3) If you are going to use the heat shrink tubing, insert it now on the end of the BLACK cable that goes to the motherboard.

4) Using the soldering iron, solder the two ends of the BLACK cable plus the end of the GREEN cable that goes to the POWER SUPPLY together.

5) If you were using heat shrink cover the joint and shrink the tube, or if you are using insulation tape, simply wrap the tape around the joint.

6) Cover the end of the GREEN cable that goes to the motherboard, we will leave that end disconnected.

7) Plug your power supply into the mains without connecting the motherboard and see if the fan starts to spin.

8) If the fan did spin, connect the PS back to the motherboard, make sure you have RAM, CPU, etc. in the motherboard, plug in the mains again and hope it will all work.

9) In case you don't have a UPS which you can switch off to cut the mains input, you can add a switch to the front of your computer to do so (see the next step).

Yeah, I know, the steps above sound a bit confusing, no? Then you can try following the pictures. If you still have trouble just leave a comment and I'll help you. :-)

How about shorting green and black wire from psu fro behind mobo ?<br>Is there any risk ?
<p>My problem in my old pc is quite related to yours, my old pc is automatically power on when I plug in to the ps box but there isn't post and display action happen. </p><p>Can I apply this method? or what cause this problem to my pc? </p><p>i really need help.. maybe you could give me some tricks and tips to fix my pc... </p><p>Thanks a lot...</p>
<p>Maybe your motherboard is not that damaged to fix it's hardware. It just maybe your corrupted BIOS chip. It's very easy to fix.<br>I brought my 8 years old dead motherboard, back to life with following method.<br><a href="http://hipstermag.blogspot.com/2015/11/how-i-brought-dead-motherboard-back-to.html" rel="nofollow">http://hipstermag.blogspot.com/2015/11/how-i-broug...</a></p>
<p>Works like a charm. I had an old-ish gaming desktop that I thought was toast but it comes in clutch as the only working computer left in the house, and hopefully will be up until I can get a new one. </p><p>A few tweaks though ;</p><p>1. You really don't need to cut at the same height, just putting it out there</p><p>2. In my power supply's case, there was at least 10 black wires. Might be more helpful to say that any works, as they all should be grounded, as some may be confused</p><p>All in all though, thanks for the guide, it was extremely helpful!</p>
<p>As much as I would like to try this, I have some questions before I lose a good PSU.</p><p>Just one, I think. </p><p>1. What kind of 'dead' do you mean in this instruction? </p><p>2. Will this work if the motherboard doesn't go through POST(Power On Self Test)?</p>
By 'dead' I mean that the motherboard does not respond to input from the front panel power button (i.e., when you press it, no fans spin up, etc.). Most motherboards have an LED on the board itself that lights up even before the power button is pressed, in my case that LED was lighting up as expected.<br><br>I cannot guarantee that this will work for you, this is a hack that was successful in my case, but your motherboard may be damaged in such a way that this hack might not help.
<p>This so useful for how start a dead condition <a href="http://www.laptopmotherboard.in/motherboard" rel="nofollow">motherboard</a>. If you provide more information it will be so nice.</p>
this is so ghetto.<br />
<p>Some times, ghetto is the way to go. (That rythmed so well tho.)</p>
I don't know what is more mental; that I tried this with my lovely Corsair PSU, or that it worked a treat. Thanks so much! You saved me a good 100+ quid, have some cyber beer :)
This mode just turn the power supply on , immediatly when you put AC power in it ... Ohh and yes , this is a ghetto mod.
Correct, but it still made the motherboard start (in my case).
if it make your mobo run then your power swich was broken<br>
Nice! Now I have a way to make one of my projects work.
Have to add this to my list of last ditch hacks to try after the warranty has expired.<br />
Interesting and useful - any idea what caused this fault to occur?<br /> <br /> L<br />
Actually I don't know what might have caused the fault, but I have also another newer motherboard which also did the same thing, but I already replaced it and moved the CPU, RAM , etc. to the new board so I cannot try it on that board.<br />
