You could also try cold spray. A can costs about $10, and lasts for
a couple of minutes. Spray suspicious chips/resistor packs/capacitors,
etc for a few seconds. You want to cool the component, but do not want
a lot of frost. The temperature change may cause a marginal part to start
working or stop working. If a component consistantly changes the operation
of your system when sprayed try replacing it. This can also be used 
to detect cracked traces.

By the way, add one more board to the list of running systems. I had
one screw-up during construction - I got the 68 pin PGA socket and
LCC socket soldered in each other's place. I wrecked the PGA socket
unsoldering it, but reused the leadless one. Luckily, the board worked 
the first time I applied power.
