This episode explains how to diagnose Power-On Self-Test (POST) errors and intermittent system lockups that indicate potential hardware problems. We discuss common beep codes, LED indicators, and error messages displayed during startup, as well as how they map to specific hardware components. Lockups that occur after startup are also examined for possible causes, including overheating, failing storage, or power irregularities.

We provide exam-focused and real-world examples, such as identifying a failed GPU through POST codes or troubleshooting a server that freezes under high CPU load. Troubleshooting steps include isolating hardware, swapping components, and verifying power stability. Understanding these indicators ensures candidates can pinpoint startup and stability issues with precision.
