Both Asus, newer one P9X79,older M3A green.
About a month ago I was using my newer pc(had it for around 3,5-4 years), at a time probably browsing something. Regardless, I decided to restart the pc. It restarted and worked for about 40 minutes, after which it tried to restart again,on it's own, but there was no post(are you supposed to write it in uppercase?). I turned it off and got inside,poked and changed some parts around(I had a spare gpu and a psu), the fans were spinning, it worked for 5 sec,then restarted and stayed on, however still without post. After a while it stopped doing anything altogether. Power button wasn't doing anything, reset button wasn't doing anything, shorting the power switch or reset switch didn't do anything, but the power LED was still glowing. As I saw in some video on youtube, seems like that means there is a short. Obviously refutable, but I am grasping at straws here.So I tried to poke around with a multimeter. That yielded nothing, since I know next to nothing when it comes to things like that.
Desperate I called the repair shop,which said that diagnostic will be free, I would only need to pair a fare for the repair tech. As it later turned out the site wasn't relevant, no prices were up to date and diagnostic was technically free, but it is not performed without additional fees. Anyway it is not too relevant,but the point is it costs me 80$ to get my pc back and carry it back on my own. At one point I was thinking about suing them, but again, ianal nor an electrician. Diagnostic didn't pinpoint the fault either. Tech said that there is a short, in the X79 chip or somewhere close to it and it's too intricate to do as is, without removing the chip.
The old pc was sometimes used for 30-60 minutes at a time,but was mostly untouched for about 4-5 months. After the newer one died on me I tried to use the old one. Didn't post either. But at least the fans were spinning right away. Again, tested the parts,single ram,different psu, different graphics card,whatever. No beeps, no post. After a while I removed the cpu fan and noticed that It was cold. Even after 30 seconds it was freezing cold. So I made a guess that capacitors could be faulty. Problem is all of them look like the day I got the pc. All tops are flat,there is nothing leaking above or underneath from the looks of it and the only flaw I could find is that 1 or 2 of them are a little too easy to move,but obviously they are still welded on tight. I don't know how to test them without an ESR meter, maybe I could do something with a multimeter,but the only way I found was to remove them and then test them 1 by 1 outside of the board. Besides I am still unsure as to what the difference is. Also I would've liked to keep intrusive stuff to a minimum, so I didn't try that yet, but so far that seems like the best option.
So I don't have money to replace the boards,especially the newer one,which one guy I know says costs 700$ in his area and I can't ask the repair shop,since they already ripped me off once and I am still broke.
TL;DR need advice on how to find a short and how to test the capacitors in board.
