I think i've got a bunch of bad capacitors "Bad capacitator plague" on this mobo I have, I was just wondering if the board would still operate properly? :S

the problem is that once the caps give in, the mos fats and the VRM´s are next,
so you have to make sure nothing else has been damaged before chainging capacitors

Bad Caps were used from sometime end 90s to 2002/2003. If you use the "electrical thing" (PC-equipment, TV, VCR, CarRadio, ...) not very often it lasts for some years without problems.
Example: two mobos with bad caps, a expensive soyo and a cheap ecs, both bought in 2002. The soyo WAS my everyday work machine, the ecs IS the data silo with four old disks and it is infrequently turned on in a week.
The soyo worked properly until beginning 2005, then it showed first little problems. Until mid 2005 it has hard problems but i had no money to buy a new pc, but then in fall 2005 it was not more possible to work with the thing.
The ecs works perfect until now but as said before, to reach the same count of operating hours as the soyo it has to run until 2020 :) But before that the bad caps will collapse because they dry out much faster than good caps, even if the cap is not on power.

Yes, bad caps can be replaced, but require English instructions for those incapable of speaking Spanish :)

The "bad Cap" plague was the result asian companies using stolen proprietary electrolyte formulas in "brand name" capacitors, but didn't make the formula quite right... there were many products affected, but most notably Abit, Asus, MSI and a few others. The caps swelled, leaked and failed, causing failure and sometimes damage to other components, but majority of boards were salvagable by replacing the caps - and still are. Some people actually profited from the debaucle... fixing boards and helping the misfortunate. Some arey are still around and still doing it.

:lol yes i know that but pics actually help:

Instructions:

heat the cap legs while pulling the caps

clean the area after removal

get similar caps to replace

resolder the caps

Hint: for self-replacing you have to have:
1) Solder iron which gets really hot, no 25W-Type, better a soldering station.
2) The special-Caps, only LowESR-Types, not the standard ones!

But the question is, is it worth to buy the mostly hard to get caps and have the effort to solder it, or buy a cheap mobo which can take the same components as the old one.

In Europe it is very hard to get the LowESR-Types, either they are very pricey because you buy them in 1 or 2 piece per muFarad-Value, or you need to buy a minimum purchase of 1000 pieces per value :)
But in USA it's apparently much easier to get the LowESR-Types.
