Leaking capacitors
When turning on my computer in the morning I have been having problems with
it booting and it was also rebooting on its own. I first restored it to a date where it was running good and then swapped the memory but neither seemed to help. Tonight why surfing the net and reading the forums I saw the same problem posted. Someone posted about leaking capacitors and when I checked mine almost all of the small 6.3v are either leaking or bulging. An article about bad capacitors also suggested that everyone take a look at there motherboards even if you are not having problems. Can I swap out the MB without reinstalling Windows XP and have it run without problems.

Actually you should be able to even if its another one but youll possibly need different drivers for certain things like the controller etc. Personally Ive had huge problem the last few times I changed the MBs. Here is the link to an interesting article with pictures: http://www.burtonsys.com/bad_BP6/story5.html Do you have an ABIT? I heard ABIts mentioned the most about bad caps but everyone hinted that many other firms were using bad caps too. Of course it makes you paranoid and you imagine that all the problems are due to faulty caps. I havent seen any leaking or bulging caps yet even on my bizarrely quirky MBs - all the ones Ive been buying the last few years. You wonder if they all have caps that arent THAT bad but not that great either. Theres a guy in the ABIT groups who talked about it a lot back then when it wasnt that well known and he has a service where he replaces all your caps. |

While I don't do it regularly, for profit, every now and then I have some excess capacitors and repair boards.. if you want yours repaired as cheaply as possible let me know... would eliminate the issue of reinstalling windows and certainly a lot cheaper than buying a new board, but on the other hand some people like the excuse to upgrade to faster equipment... to each his own.

Any suggestions on where replacement caps can be ordered from for a
reasonable price? Last time I tried to find some the best I could do was about $10 for caps and $15 for shipping! BTW, I'm in Canada... "kony" wrote in message ...

Try a local TV repair shop or someplace like Radio Shack

Normally I'd agree, but here in Calgary even the electronics shops don't
seem to have the ratings/sizes of caps that you find on mainboards. RadioShack here doesn't even carry capacitors at all!!! (There's about a dozen stores here in town) "DFC" wrote in message ...

BTW, I'm in Canada... On a regular basis, as-in, right now, no I don't know where to get best prices on particular caps, though $10 sounds about right for a dozen, not 6... Parts like those go down in price with volume purchase. The place I'd advise someone to make a small, one-time purchase would be http://www.digikey.com . In volumes of 10-99 pieces you can get 8-10mm OD 1-2K2 mF (most common sizes needed) caps for ~ $0.50-0.85 ea. http://dkc3.digikey.com/PDF/T041/0722.pdf You might find misc. caps as surplus on the 'net too, possibly at lower price, but be sure of what you're buying, model/specs, dimensions, and how old they are... some brands have easily decipherable date-codes on the label, though I guess any reasonable age of "new", good brand cap would beat a generic that's vented. :-) |

Radio Shack does not stock appropriate parts though I don't know about their parts-ordering service (but again it's likely they'd want a $mall fortune). There's more to it than merely correct size, voltage and mF rating, more importantly they must have acceptable properties typically found in so-called "low-ESR" capacitors, low impedance, high ripple capacity, high (105C) temp rating, etc. To a certain extent the mF rating and voltage are irrelevant, as the values most often used generally far exceed requirements but are what's inherant in the physical can size used to give greatest performance per $ in the other critical specs, and board real-estate, in an aluminum electrolytic variety. Odds are that any capacitor not promoted as suitable for switching power supply use will be even worse than the originals (which failed). |

BTW, I'm in Canada... Hey I once had a quantum HD that used micro jumpers. Where I live they arent sold anywhere and I took them off to use it as a master. Then I needed to slave it and couldnt find the jumper. I paid $15 shipping for some .10 micro jumpers from San Fran, truly disgusting but thats how bad it was even 5 years ago here. The guy they call Homie or something in the Abit groups has a website. See how much his fee is. He points out you need special tools and skill to do those micro solders nowadays though some DIYers have tried it. |
