Is it common for the cable on PC speakers to cause the PC to close down
randomly if it is old or damaged?

No, it's practically unheard of. At worse if the cable were
shorting out it might overheat the codec chip or gain stage
opamp (output on the motherboard) though these days those
chips may have overload protection, but it would not shut
off the system, only the sound output.


I noticed my PC shutting down at random,
and if I move the speaker's cable with my hand intentionally just slightly
(with the power cable inserted into it of course) that it makes a slight
buzz noise and the PC shuts down. I'm not using the PC with no speakers now
and it seems to be working fine - do you think it's the speakers that were
causing the problem?

I'd tend to suspect what badgolferman suggested, that your
sound card might be loose, moving around a little. You
might open the case and check on that.
