Yes, absolutely! Answer them (once).
The ideal way to handle endless variations of the same trouble-shooting questions is to create what we call "canonical answers" — comprehensive guides about what users should do when they hit these commonly-asked crashing and performance problems.
Users keep asking these same questions in various ways because it is difficult for the author to know exactly what they are asking about… much less how to find the solution on the site. So they become numerous (and somewhat annoying) because you find yourself asking and answering the same basic set of followup questions ("Did you try X,Y,Z; could it be L,M,N,O or P?").
When answering these canonical questions, do everything you can to really overkill it. Write a detailed, step-by-step, ultra-clear guide with screenshots and examples. Those questions will become ultra-popular, brining in lots of traffic from search engines as folks search for this stuff. And every question you close as a duplicate of the canonical answer, you create yet another entry point to the site covering all the variations of how these questions are asked. If you continue to have great answers like you've provided thus far, you stand a good chance of attracting some great new users who will add value for years to come.
