Honestly @the_joel, those structured guides can help keep a chat from just going in circles.

Honestly I start by assuming I'm an idiot, lmao. My first thought is always some grand conspiracy but it's usually just a loose cable or a setting I clicked by mistake. I try to swap out the simplest parts first, like power supplies or cables, before I even consider anything fancy. If the problem goes away with basic stuff, you saved yourself a huge headache. If not, then you can start down the rabbit hole.
