The upshot of this was that I took the offered advice, checked around for
shorts, and powered up with a new psu. As the pc has a lousy chipset, an
awkward soundcard, a slow cpu, no information of value on the hard disks and
a nightmare video chipset, it all worked :-P. If they had been decent parts,
they would have died. I'll let memtest86 loose on it soon - just to check the
cpu end out.
