I have two EDPs and I've noticed over the years that sometimes the memory SIMMs (or whatever they are, DIMMs?) get unseated or oxidized or something and need to be re-seated. When they get loose all sorts of strange behavior occurs. I also had one of these (memory SIMMs) go bad once. Again the problem manifested itself in all sorts of strange ways. As the last poster mentioned, EPROMs can also become unseated and cause evil to occur.
