I wasn't thinking commercial, either.

An expert system is what you originally described -- an interface that uses a binary tree or other decision pattern to diagnose and offer solutions for a problem. Like Windows' diagnostic help thingy -- you choose from a category of problems and it starts with the simplest solution asking "did this work?" or something like "did this produce <X> or <Y>?". It then drills down to more complicated ideas until the expert system is exhausted. The lowest level is "please ask someone" -- in this case, "post your query to PM".
