Can't help you with Malaysian sources (there must be some hobby shops in KL? ) but this is no doubt a result of the infamous counterfeit electrolyte scandal.. the formula for electrolytic cap electrolyte was stolen and copied, but the formula didn't include some vital additives- ones that in low-Z caps stabilize them. You can get replacements from Digikey in the US. Actually, I'm just about to order 10 pieces for a Soyo motherboard that blew up (2 of them burst- "Wendell" brand) 1000uF/6.3V. If you want to send me some $ to cover the cost I'll order some extras and throw them in the mail to you. http://ca.digikey.com/scripts/DkSearch/dksus.dll?KeywordSearch Panasonic 1000uF/6.3V Best regards, Spehro Pefhany --"it's the network..."

Interesting, when my ABIT KT7A-RAID blew up (13 JPCON 2200uF 6.3V leaking caps) I found two of the power diodes (presumably in the proccessor core voltage regulator circuit) to be soldered incorrectly and not making contact with the pads. I just assumed that caused the caps to burst. Maybe they weren't related? I just replaced the whole MB, I keep it on a shelf to remind me that paying more doesn't neccesarily mean you get better product. -Denny > I had a similar problem, 5 burst caps on an MSI motherboard also.

Some motherboard diodes get hot enough to de-solder themselves if the case isn't properly cooled. Happened to me a few times with a particular motherboard design. -Adam Denny Esterline wrote: {Quote hidden}>Interesting, when my ABIT KT7A-RAID blew up (13 JPCON 2200uF 6.3V leaking >caps) I found two of the power diodes (presumably in the proccessor core >voltage regulator circuit) to be soldered incorrectly and not making >contact with the pads.
