At the moment, shockingly, the machine has stayed alive nearly 20 hours,
which is longer than it has done since this started happening.

The Windows PC, surprisingly, is still alive one day later, surprisingly,
simply from (apparently) just removing two memory cards (and not even odd
or even cards - but simply two adjacent memory cards at that).

I find it hard to believe we zeroed in so easily on the culprit, but I'll
keep the PC alive for another day just to make sure, before running full
memtest86 tests (as suggested by n/a & Paul) on all four memory sticks.
