Check your capacitors !

I had 11 leaking capacitors on my old Epox (was still working believe it or not) which was replaced with a new DFI board,both Abit and Asus are now using high quality capacitors in their boards ,however not all companies are taking the same measures.
 
Wow, that's like 2 year old news. After having capacitors blow in about 8 computers years ago I can't believe you hadn't heard of it before.
 
The first article doesn't surprise me about MSI.

We had a thread a couple weeks ago about MSI's reliability here.

Almost all (50) of the systems that I work with that had MSI motherboards have developed leaking/bursting caps.
 
and once again... that had little to do with MSI and everything to do with capacitors that 'should' have had nothing wrong with them, but were built with an incomplete formula... Every company that used those capacitors had problems, and no company that didn't had widespread problems. Holding this up as an example of why you don't like MSI is like claiming that the exploding firestone (FTR: a japanese company) tires on Ford explorers prove that Ford makes bad vehicles.
 
Thanks for the link, but the whole 'bad capacitor' topic is old news. Just a warning - you can't use any old cap for replacement. They need to be speced for use in switching power regulation circuits (usually very low ESR and high ripple tolerance). Better to RMA your mobo wherever possible than to attempt replacing them yourself - I maintain that this type of defect should be covered even out of warranty.
.bh.

3chord - It is evidence of a willingness to cut corners on parts costs. Or would you be willing to suggest that these substandard parts didn't cost less than those from known good suppliers like Sanyo, Panasonic or Nichicon...

Hows it "old" news when even the "new" ASUS K8V is affected by these leaking caps?

I bet that instead of finding and destroying the defective capacitors, some were "disposed of" by way of being sold to other companies.
 
It maybe old news but is still going on. There are recent boards with the problem (such as the K8V from ASUS).

I would think that at least ASUS and Gigabyte would not be affected and surprisingly they too try to cut corners with "el-cheapo" parts.
All kinds of board names have been sited with problems (ABIT, AOPEN, ASUS, BIOSTAR, IBM Netvista, MSI, EPOX, SOYO, GIGABYTE, INTEL, ECS, DFI, SHUTTLE, SOLTEK)

Maybe it is time to seperate the wheat from the chaff... I haven't seen any complains with Iwill or Tyan as of yet.
 
You bet it's still going on, it's all cheap chineese caps, they still use them, some hold some don't. They certainly hav'nt switched to japanese caps on any of the sub $300 boards I've seen, too expensive. What makes you all think they have the "formula" or "manufacturing" process now? http://www.spectrum.ieee.org/WEBONLY/resource/feb03/ncap.html



I love this CYA quote from the first article linked

"?Starting from October of 2002 ABIT made significant changes with the goal of producing the absolute most durable products available on the market,? "

Bit of hyperbole no?

It may be old news but you`ll be surprised by how many people still don`t know about this "2 year old news" and has other members here have meantioned, it still happens even on newer boards.
 
I had an old Shuttle SV-24 system that I was about to just throw away because it was constantly locking up. Replaced 6 puffed-up caps with a $2 bag of high-temp caps that were rated twice as high, and the thing magically started working.

That was a year ago, though, and even back then it was very old news.
 
An article on ABIT-USA.com saying that ASUS has inferior quality... Now that doesn't sound biased at all 😛
 
Anyone ever have this problem on an asus cuv4x board? I have one with occasional lockups, which I've always blamed on windows 98... probably manufactured in early 2000. It's kind of an outside possibility, since the board is normally quite stable, but once in a whole, it locks (i.e. hard reboot) 3-4 times in the space of an hour... then runs fine again for weeks (24/7).

LOL. No I posted it just to show one manufacturer is hailing japanese caps. They also claim to use them exclusivly now even though thier language leaves a little wiggle room.

"ABIT led the industry in making this switch, which resulted in all its mainstream motherboards being fitted with 100% Japanese capacitors. Although the cost of the Japanese capacitors are several times more expensive than competing capacitors made in China, the quality level is unquestionably better. "

I'll check when I get home if my NFS-7s has japanese caps.
 
I was walking across the deck of a guided missile destroyer carrying a plugged-in Fluke differential voltmeter in 1964 and two electrolytic capacitors blew up with a noise like an M80 and electrolyte sprayed out through the cooling holes. Electrolytic caps have been leaking, bulging, drying out, and exploding from the day they were invented. Some of the larger physical sizes incorporate safety valves. The only reason they exist at all is that they are the best way to achieve a high capacitance in a small package. Anybody that knows electronic equipment repair looks for electrolytic caps at the first sign of trouble. In high power, high heat applications long lived electrolytics are the exception and not the rule.
 
Here is a tip that I just found out (special thanks to Carey Holzman).

If the capacitors have a "K" etched on top (instead of the traditional "X") then they seem to be "good" (no leak reports have been sited)
 
I had a bad batch of abit's with dodgy capacitors. I noticed that some of the caps were bulging and some had leaked.

I quickly cleaned up the boards, pushed the tops of the caps back down, and ditched the boards on ebay.
