I start within the program that is giving me trouble—in the Preferences and Help files; Then I’ll go to the manual (if one is available in hardcopy or online) and then to the manufacturer’s website; If I have no luck with that, I’ll try an internet search engine to see if I can find an online forum or something that references that problem; last ditch is to pose such a question (only after I’ve looked to see that it hasn’t already been answered) on a forum specific to that product, or eventually on a general forum, such as ask-public. I’m not very knowledgeable about computers, but I am good at finding resources as outlined above; so when someone does ask a question specific to a particular product in a general forum like this, I will typically direct them to a forum related (after finding it via a web search) to the issue they have, so they improve their odds of encountering someone who can answer their question.
