Windows 7: Soldering motherboard capacitors

Soldering motherboard capacitors

Hello,

I once created thread in Crash sub-forum, where I complained about frequent BSOD's and freezes. I now took a closer look of my motherboard and found 5 capacitors that are bulging, where only 1-2 has this brown thing on top of it.
I don't have special equipment, but since sending MB to repair service costs same much as buying new motherboard of same time, I will try to replace capacitors by myself. And I have some questions about it:

1) Can I use regular soldering iron ?
2) Do I have to use any liquid on motherboard=> 3) Can I burn a hole (melt) my MB with soldering iron without using any liquid ?

Thank you

First off I would suggest investing in the right tools for the job. Something like this.

I took a closer look and found out that 5 capacitors of same type are all kaput. 1000uf, 6.3V. Why's that ?

I know this is an old thread, I have a quick question.

A capacitor has a long end and a short end, on a circuit board there usually is a circle where the capacitor goes on, one side of the circle has lines that are diagonal the other side has nothing. What side is the negative and what side is the positive ?

Long end is usually positive side of capacitor. There should also be a marking on the capacitor itself (usually large "-" rectangles showing negative side). On motherboard the white lines indicate to the negative side, there's also a "+" sign next to the clear area indicating the positive side.
Match capacitor's positive side with motherboard's positive hole NOT vice versa.

I see the negative side on the capacitor. Didn't know that
