In case you haven’t heard about it elsewhere, there are some recent motherboards having problems with leaky capacitors.
Basically, the problem is the electrolyte in the capacitors becomes chemically unstable, the capacitor pops and starts leaking, the capacitor stops doing its job, and system stability falls out of the sky.
An EE can do a better job of explaining what a capacitor does, but in my very limited electronics background, every project I ever did used capacitors to eliminate noise or smooth out current.
Abit has come out and acknowledged the problem, but other manufacturers are also said to be affected, including Asus. So this isn’t a problem limited to cut-rate boards, although it wouldn’t surprise me if the cut-rate boards also are affected, because the issue stems from cheap Taiwanese knockoffs of a costlier Japanese design.
Identifying problem boards can be difficult, because the affected caps generally are unlabeled, but not all unlabeled caps are problematic. And, as you can see, my usual advice of sticking with a big-brand motherboard doesn’t save you in this case.
I recall a few years ago an article on one of the newsy tech sites like Cnet or ZDNet said some older models of Soyo motherboards could develop this problem. At the time, Soyo declined to comment. So this isn’t exactly a new problem. If anything, it seems to be cyclical.
If you do have a board that develops the problem, you can probably get it replaced under warranty. If not, a skilled technician can de-solder the bad caps and replace them with higher-quality ones. One technician who performs the service charges $50, which seems very fair to me for de-soldering and re-soldering 28 connections.
It’s definitely not a good first electronics project to try yourself though. If it’s something you want to learn how to do, practice on an old, obsolete motherboard or modem or sound card first. And, naturally, I won’t claim any responsibility.
If you develop the problem, this could also be the excuse you’ve been looking for to upgrade, seeing as it’s getting easy to find new motherboards for $60 or so.
