PC repair roadmap
Use this path when a PC problem feels bigger than one article but smaller than a full tear-down. The goal is to sort the symptom family first, then move through the right guide and live flow without piling on random fixes.
2. Use the smallest safe next test
Move one step at a time so the repair path stays readable instead of turning into guesswork.
3. Decide whether to stabilize or escalate
Once the PC starts moving again, choose whether this is a tuning problem, a build mistake, or a stop-and-review moment.
