A PROPERLY WORKING UPS will not cause problems. One which is itself
causing power glitches, or which does not adequately suppress mains
glitches, can be a problem.

Umm, no.

Well, let's say the #1 cause of problems in all equipment is connectors
of various sorts. The first step I take is always to shut down, power
down, remove the power cord from the mains, and wiggle/remove/reseat
all connectors, like power connectors to floppies, hard drives, CDROMs,
control cables to same, all expansion boards get removed and reseated
(including memory and CPU), etc. Only after this would I run any
software intended to diagnose hardware.

Or overloaded. Overloaded PSs cause problems.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
