The sarcasm isn't necessary. There are many weird, hard to find,
state-based problems that disappear (for now) with a power cycle,
because power-cycling brings you back to a known state And those
state-based problems are exactly the ones that take forever to solve,
because they're state based.

If you absolutely must find the exact root cause, then you can't power
cycle the computer, and instead must spend hours or days finding the
root cause. But if you need to get back to work and can live without
identifying the root cause, power cycling can either rule out these
weird state based problems, or remove the symptom. Either way you're
much better off.

In the words of the late Phil Barnett, "While it would be nice to spend
days figuring it out, I spent minutes and got past it."
