    Please, my friends (zen.state) more advice needed.

    My nice old G4 has lately been exhibiting weird behaviour: freezing, failure to boot . . .

    The change in behaviour was co-incident with the heat here in Vancouver; that's when trouble started coming. But this morning it is nice and cool, and I had to try three times to get the old girl running.

    I don't do anything out-of-this-world on my computer. Run itunes, edit photos (GIMP), that's about it.

    Is there an initial diagnostic I can run to see what's up? Or some magic freeware that can clean up the little pile of digital pooh that's causing this?

    Thanks.

    Well, I don't really know what a logic board is.

    Is there no OS X diagnostic routine that might point to the fart at my dinner party?

    A logic board is a very important part of a computer that can cost up to $1000 to replace. Usually when a logic board dies in a computer (or a Mac anyway) its not worth replacing, so a new computer is purchased.
