Reseating boards is one of the most common and effective appeals for a
miracle! Observe anti-static precautions!!!!

Another handy bit of maintenance is to use a vacuum clearer to remove
the dust bunnies from inside the machine. If you don't have a vacuum
cleaner, get one. If you can't manage that, try to take the machine
outside and blow the dust bunnies out with canned air.

Given sufficient time, every spec of dust in the computer room will come
to rest inside one of the machines! Things run a little cooler when not
under a blanket of dust. Most chips work a little better and live a
little longer when adequately cooled.

PC's and workstations do not live in a controlled environment and they
tend to collect all the available dust. They too can benefit from a
periodic blow job! ;-)
