After symptoms pointed to a failing power supply, a technician replaced it and used CMOS utilities to test. What troubleshooting step was performed?

• A. Document the solution only
• B. Verify functionality and implement preventive measures
• C. Reinstall the operating system
• D. Upgrade the motherboard firmware

Answer: (B)

After replacing a failing power supply, the main goal is to confirm the system powers on, runs reliably, and remains healthy. Using CMOS utilities means you're checking the hardware health directly in the BIOS/UEFI—verifying voltages, temperatures, fan speeds, and other sensor readings to ensure the new power supply is delivering proper rails and the system is stable. This step also includes applying preventive measures to reduce future issues, such as confirming default or safe BIOS settings, ensuring voltages stay within spec, and making any small configuration tweaks to protect against power-related problems. This approach fits best because it moves beyond a one-time repair and focuses on ensuring ongoing reliability. Reinstalling the operating system isn’t indicated by simply testing with CMOS utilities, and upgrading the motherboard firmware isn’t a direct consequence of testing the new power supply. Documenting the solution is useful, but it doesn’t address system functionality or preventive actions.
