One thing I have not seen mentioned thus far is the possibility of a poor ground connection of the motherboard, or even an intermittent short to ground somewhere. Just as important as stable voltages supplied by the PSU are proper ground connections. Check with a meter -and the falcon powered off- the impedence between the +5v lines and the ground contacts. You should be measuring 2-5M ohms. If not, that's bad. Conversely, the grounded TPs should all read 0-100 ohns measuring between them. It may not be a power line shorting, but a ttl line somewhere. This would not necessarily harm the computer, but it would cause all sorts of logical wackiness. Make sure all you ground point are clean, not rusted, and not stuck together from corrosion (Falcons are old machines, afterall). Just something to consider...
