In decades of troubleshooting various systems, I can probably count on the fingers of my hands the number of times a problem was caused by more than one thing at the same time.

And most of those were "catastrophic" failures anyway. Lightning, surge, that sort of thing.

Occam's razor says it is caused by only one thing, too.

The real skillset involves the detective work that consists mostly of *process of elimination*, *isolation* and *critical thinking*.

And avoiding doing the same thing over and over. Because you've already proved it ain't that...
