I've tried many times to get to the bottom of a problem using that BSOD debugger, and never yet succeeded. I don't think I have the patience (or is it the luck?) needed.
Sometimes there's useful information in the event log; sometimes I poke chips and it crashes, telling me which one to unplug and reseat. Sometimes the reinstall-repair fixes it.
Most often, I describe the problem on a forum and a kind person who knows pops up and tells me exactly what to do. Once I've learned how to fix a particular problem, I remember for hours!
