Question

A technician receives a PC that frequently shuts down and has extremely loud fans. When the technician begins a stress test, the PC shuts down almost immediately. Which of the following should the technician do next?

Options

• AInstall a liquid cooling unit in the computer.
• BMonitor the core CPU and system temperatures.
• CReapply thermal paste to the processor heat sink.
• DClean and test all fans to ensure proper airflow.

Explanation

A PC frequently shutting down with loud fans, especially during a stress test, strongly suggests an overheating issue. The technician's immediate next step should be to monitor the core CPU and system temperatures to confirm overheating and identify the specific component causing it.

Common mistakes.

• A. Installing a liquid cooling unit is a drastic and expensive solution typically considered after diagnosing and exhausting other thermal management options, not an initial troubleshooting step.
• C. Reapplying thermal paste is a corrective action for overheating caused by poor thermal transfer between the CPU and heatsink, but it should only be performed after temperature monitoring confirms a CPU overheating issue.
• D. Cleaning and testing fans addresses potential airflow issues, but it's a corrective action that should follow the diagnostic step of monitoring temperatures to confirm overheating is indeed the problem and not something else.
