sometimes you can weed out the faulty caps
by looking in where things get hot around
these caps such as voltage reg's on your
motherboard.
i replaced 2 caps in a p2-266 the other day
2 1000uf 10 volt neer the voltage reg's, due to
heat from them, the caps were leaky and upsetting
the voltage rails, the system will not boot.
