Which manufacturer made yours? What brand is the bad cap? How many of that type are on the board? If only one or a few alike and your eyes are still good, it might be fun to try DIY, something different anyway.
This is an Abit-KT7 board. Probably one of my longest running board ever.
The bad cap plague is the primary reason why Abit no longer exists. :-(
(although I have tried to boot the old 386/33 in a while). I've been tempted to try the cap replacement my self, but I have never experimented with a "solder sucker" and while I am handy with a soldering iron at the "wire level" (and I have fixed an few power-connector problem on Nvidia cards), I haven't dropped to the mirco-level of capacitors.
Any suggestions on a solder sucker? I always envisioned something like a baby-nostril sucker that has a heat-resistent tip where you melt the solder as best you can and suck the melted solder out of each prong solder hole and then solder a new cap in.
I guess with this old board -- "I got nothin to lose..."
Let me know if you have an suggestions in the sucker tool department.
I always replace all of same type, as suggested on badcaps.net, best place I know to look for help with such things. Typically motherboards have one or two bunches of 3-8 identicals near the CPU socket. If that's where your bad one is, do all of that type, and if there is a second bunch of identicals near the socket, and if the board is really worth reviving in the first place, consider doing those as well, especially if the same brand as the bad one. Vacuum-type desoldering tools for me are unusable. I always use wire wick desoldering braid, usually .075" wide, usually along with flux paste, both readily available from the suppliers of quality cap replacements mouser.com and digi-key.com where I get all mine. Adding solder before trying to remove any is often the only way to wick up enough from the tiny motherboard holes to gain release on both legs. RoHS-compliant lead-free OEM solder can be a big pain. Before you try, you might want to peruse the badcaps.net FAQ on the subject. Good luck! -- "Wisdom is supreme; therefore get wisdom. Whatever else you get, get wisdom."
