In that I don't have ubuntu on the machine
anymore, and haven't for awhile,
I'm a little bit surprised that it's there. I do not know which of the
other three I should keep. Ever since the big BIOS rejiggering of a decade
ago, what once was clear has been a mystery to me. So in addition to not
knowing which one(s) to keep, I have no idea how to get rid of any I don't
want or need. Suggestions, advice, or knowledge from the above?
1 & 3 are fallbacks that should have no need to disturb. As Ubuntu is no longer
present on the system, then can be removed using efibootmgr, which provides a man
page.

strangely, memtest no longer appears in my grub menu,
and i have no memtest
executable.
memtest86+ is in the boot menu of most GNU/Linux installation media. There's also
memtest86 in both free and nonfree versions that I have more faith in for use with
UEFI PCs and Macs using DDR4 and newer RAM: https://www.memtest86.com/

Dr. Klepp left PSUs out of that list.
we'll see if it repeats. i very much hope it
doesn't. i wondered if a log
i've had running -- a ping every three seconds with the result written to
disk -- might have stressed something. and it has on occasion over the
years suffered from what seems to be something overheating, such as when
it tries to compile a heap of nvidia modules.
Failing electrolytic capacitors are notorious causes of random system failure.
Most caps on motherboards made around 12 or less years ago have been replaced by
polys that are magnitudes more reliable. An Asus from 2013 probably has only
polys, or polys for all the most important ones. OTOH, you're unlikely to find
anything but electrolytics in power supplies and various addon components. If your
PSU is out of warranty, get its cover off to inspect for leakage and swelling. If
you find swollen tops, or obvious leakage, not to be confused with splattered
glue, they or your PSU need to be replaced. Not all electrolytics manifest obvious
signs of failure. Major brand names are not a guarantee that any given PSU was
made entirely of quality parts to start with. Cheap PSUs often provided with
budget cases are unlikely to have any quality caps. Visit badcaps.net for details
on evaluating what you find.
