Question 69

Turn off the computer to check the components.

The first action a technician should take is to turn off the computer to ensure the safety of both the user and the technician. This step prevents potential damage to the components and reduces the risk of injury while investigating the source of the grinding noise.

A) Use compressed air to clean the computer's fan.

While cleaning the fan may seem like a reasonable action to address noise, it is not the safest first step. The grinding noise could indicate a malfunctioning part that might cause further damage or injury if the computer remains powered on during maintenance.

B) Turn off the computer to check the components.

This is the correct choice, as turning off the computer is essential for safety. It allows the technician to safely inspect the internal components without risking electric shock or damage to the hardware that could occur if the system remains operational.

C) Back up the computer's hard drive.

Backing up the hard drive is a critical task, but it is not the immediate priority in this situation. If the computer is making a grinding noise, it could indicate an imminent hardware failure, making it unsafe to proceed with data backup before assessing the hardware condition.

D) Contact the vendor to check the warranty status.

Contacting the vendor regarding warranty status is not a practical first step in this scenario. The immediate priority should be to ensure the computer is safe to operate and diagnose the problem directly, rather than deferring action to warranty inquiries.

Conclusion

Turning off the computer is the most appropriate first response when faced with unusual noises, as it prioritizes safety and allows for a thorough inspection of potential hardware issues. Other options either delay necessary action or address non-immediate concerns, thus failing to prioritize the technician's and user's safety effectively.
