A common problem amongst single processor G5s was that the plate of metal soldered to the Logic Board connecting all eight of the RAM slots would, over time, expand and contract in such a way that the computer could not boot properly, as it would not detect any RAM. The only way known to fix this problem is for someone to re-solder the plate themselves or expose the other side of the Logic Board to heat from a heat gun. The latter of these two options is far easier, as to access the plate of metal one would have to completely remove the Logic Board from the computer, whereas all one has to do to expose the other side is remove a fan.
