CompTIA A+ Core 1 (220-1001) — Question 278

After replacing a failed mother board in a user's computer, the technician receives a report that the computer is behaving erratically. The user states the computer shuts down randomly throughout the day and freezes frequently. The technician performs a memory diagnostic, and it reports no issues.
Which of the following should the technician check NEXT in troubleshooting this issue?

Answer options

• A. Reseat the memory and reset the BIOS to default settings
• B. Add heat sinks to each installed memory module
• C. Enable overclocking functionality in the BIOS
• D. Ensure all case fans are plugged in and working

Correct answer: D

Explanation

The correct answer is D because ensuring that all case fans are functioning is crucial for maintaining proper airflow and preventing overheating, which can cause erratic behavior. Options A and B may help but are not the immediate next steps after confirming memory is functioning. Option C is not advisable as overclocking can lead to instability and is not a solution for the reported symptoms.
