Before you start fixing a crashing PC, you need to know what you're actually fixing. "My computer keeps crashing" isn't a diagnosis — it's a symptom. This guide will walk through the free, built-in signals Windows leaves behind so you can name the problem before you touch it: the bug check code on a blue screen, what Reliability Monitor and Event Viewer are quietly recording, and how to turn all of that into a precise description of what's going wrong.
This guide is still being written. The full step-by-step is on its way. In the meantime, if your PC is crashing and you'd rather not diagnose it yourself, I'm happy to help.
