| 355721 | 2005-05-16 09:29:00 | I recently (8th May) queried a problem re complete lock up. Have now had time to start investigating, and the first thing that was immediately apparent is four 3300uF/6.3v capacitors that have leaked at some time. Dry now, and no evidence of damage to motherboard (GigaByte). Has anybody had any experience replacing caps'? Others of differing values don't appear to have suffered. Thanks AG |

| 355722 | 2005-05-16 09:38:00 | How old is the motherboard? Do a google for leaky motherboard cap's. You'll find a whole heap on the issue. The upshot is, someone thought they could make capacitors cheaper than a competitor by copying their design, but got it wrong. Some motherboard manufacturers jumped at the cheap cap's which eventually proved to be dodgy. Try for a replacement, I believe some have been replaced out of warranty because such a big stink was made about the whole affair. If that doesn't work, do a search of the forum, at least one person here has successfully replaced cap's on their board (a second hand one, IIRC). |

| 355724 | 2005-05-16 21:42:00 | I've replaced lots of capacitors with roughly a 70% success rate The 30% failure is probably due to my poor soldering skills Source the new capacitors and get someone else to solder them for you if you're not confident |

| 355727 | 2005-05-17 02:12:00 | The risk is mainly due to a lack of desoldering skill . Multilayer boards have plated "eyelets" in all the holes, which make connections between the layers . Too much heat, or physical stress can break them . Both can easily happen when removing components . Most boards these days are stuffed (technical term ;)) by automatic machines, and the soldering is by machine too . That's why they are so reliable (except when people go to another employer carrying a stolen recipe for electrolyte) . The holes for leaded components are smaller than those used for manual insertion, so it's harder to suck out the solder . My technique for removing parts when it's the board that is valuable, rather than the components, is to cut the leads so that I can remove one lead at a time . It might be a bit hard to get under the caps to snip the leads, but it's probably possible to destroy them (by crushing, rather than wrenching) . |
