    Well, there's the old story about the non-multi-sync monitors that you could
break if you switched the mode too fast.  There is also the old hard-drives which
software could tell the read-head to ram itself into the disk then spin.  Both of
these aren't an issue on modern machines, but I'm sure there are very subtle,
difficult to arrange ways to destroy hardward on modern machines.  I can actually
think of one way right now:
My machine's BIOS can control the voltage applied to the processor.  If I were to up
it from 2V to say 5V, I would break something very quickly.  And I know that software
can change it, because the motherboard vendor bundles some that could do just that.
