Motherboard cap's issues

Jon Slaughter · 2010-02-04T21:57:30+00:00

One of my motherboards quit working, the effect being video corruption like issues and lock up. I looked at the motherboard and noticed 3 1000uF/16.3V caps were bad(all the tops were bowed out and one had some black residue below it). I replaced them with one 1000uF/100V cap since they were all in parallel. This allowed the computer to function normally again but the cap is getting rather hot(obviously the issue before) and will eventually fail again.Of course I already have a new MB on the way but I'm curious as to what is causing this as I imagine it is an easy fix. Something seems to be either shorting out or supplying a rather large voltage. The caps are near some large mosfets which obivously have something to do with the cpu power(they are near the extra V2 connector that gives the cpu more juice).Any ideas what is the most likely cause of such an issue? My guess is either the mosfets, something causing a short, or potentially a cpu issue(it is not overclocked but something may have failed and put it in such a mode causing excess power usage). I have tried different power supplies and graphics cards with the similar issues. I've checked the mosfets near the caps and they all look fine although I'm not really sure what exactly there function is(such as regulation or current limiting, etc...)

F*ck You! Take your piece of s*it ass off this thread. I have every right to do it how I please. It's my s*it and I can screw it up if I want and I don't need some two bit engineer acting like he knows best!

Now wait, he may be a 2 bit engineer (I have my doubts about the engineering part) but, he most likely is using a 32 bit computer, that makes him eligible for a total of 16 comments. Of course, if you want to perform some ROR, ASR or logical masking, One can then reduce his eligibility to make much fewer comments. Leaving out of course, any carrier flags to prevent any credited points!

That was my one bit comment of the day and may the Bit flux muster be with you.

Whats the point of asking a question if the answer doesn't matter anyhow...

Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico@nctdevpuntnl (punt=.) --------------------------------------------------------------

And you do not recognize that as hack technician way of getting things = done? Read also as "quick temporary fix", or "quick patch". Not really an = enduring=20 solution.
