Default hardware monitoring at the most basic level …

What? Is your hardware changing on every day basis? :-?

Ah. I see :-)

It is very odd having a system that shutdowns by its own in two different
computers. Are both boxes sharing/using the same piece of hardware?

Anyway, a shutdown denotes a critical situation, that can be true or
somehow biased but there's something that instructs your system going
down and at a first glance, on the hardware side, I would point to the
CPU temperature or a bad power supply. On the software side, a bad/
incorrect measurement of sensor trip points can also make the system to
think it's hotter than it is in reality and thus triggering a system
shutdown.

When that happens, run "top" and sort the values by CPU load percentage
(pressing "C") to see what's the culprit.

You can run a specialized LiveCD for these kind of tests (Inquisitor):

You mean George Orwell (Eric Blair) surely?
