You probably have Chinese- or Taiwanese-manufactured capacitors in that unit, which are not as reliable as Japanese-manufactured capacitors. If you search the net you will find lists of known-unreliable capacitor manufacturers.

robert, aldo,

if you run a google search for 'bad caps' or 'bad capacitors', you will find
a large hit score.

most of hits will relate to a stolen recipe for capacitors that was missing
all ingredients.

it is primarily in asian countries and mainly lower level companies.

this hit mainly with mainboards and power supplies, along with other hardware
that use low cost capacitors.

this problems has pretty well ended, but when you make repair, do use a high
quality brand. radio shack does not fall with in high quality definition.

order from a local supplier, or a well know catalog supplier. small adds in
back of electronic magazines do not qualify.

also, be sure you check diodes as caps are known to take them out also.

when you clean board, be sure you get all of crud off board and hope that
no hidden corrosion has started.

yes. i am a 'hardware head' and i have seen this problem, even with an abit
mainboard of my own.

much luck.


Digikey (http://www.digikey.com/) has good capacitors and a good selection at decent prices, and a little research on the bad brands will help you find more on that. For electronics, on the chip side, octapart is a good resource as well (http://octopart.com/)
