Question 1

A user's laptop suddenly shuts down when running high-demand software. What may be a possible cause?

Correct Answer: Thermal shutdown due to inadequate cooling.

Abrupt shutdowns during high-demand tasks often signify thermal issues. Other options might lead to performance problems or errors, but they don't generally cause a sudden shutdown.

Question 2

A user reports that their computer is frequently overheating, which is causing performance issues. What action should you take?

Correct Answer: Clean the dust from the computer's fans and case.

Cleaning the dust from the fans and case will improve airflow, allowing the computer to dissipate heat better and preventing overheating. Other answers are not directly related to the overheating problem.

The most common reason for no sound is the audio output device being muted or disabled. Always ensure the device is enabled before pursuing other solutions. Remaining options may not directly address the issue or are more complex steps.
