Motherboard died, capacitor issue?

[chackonman]

Hi Guys,

Just wanting to know how i can fix my motherboard, its an X79-UD5 from Gigabyte. One day (happened couple months ago so i got a new CPU/Mobo now) when i tried to turn on my PC it wouldnt start, i looked through the glass window and saw no light on the manual start button on the motherboard.

I unplugged the power cord and waited a couple moments while pushing the on button on my case to drain whatever energy was left and then re-plugged in the power cable, i saw the motherboard light light up again, but it stayed lit for about 5 seconds then dulled down, i did the same as before but this time it only stayed lit for 3 seconds, then 1 - 2 seconds.

So my guess is one of the Capacitors died, how can i figure out which one? And what can i replace it with? I do have a soldering iron but don't want to try anything without some guidance on a testing method and a proper replacement.

Lets get one thing off the bat, and I mean no offense. There is a huge difference between having a soldering iron and having the ability to repair a motherboard. Repairing a motherboard requires EXTREMELY precise soldiering (that is done by a machine at the factory), you will not be able to do it. You're welcome to try, but I wouldn't risk the rest of my parts with it.

Just to humor this though the 2 ways you can tell if a capacitor is bad is if its bulging outward, or you see a burn mark under it.

If you see that, buy a new motherboard.

Those are solid capacitors and they don't bulge like old electrolytic ones did. Unless they are visibly burned ou
ut only way to check them is with special instrument or by replacing one by one.
