• C. Remove and reconnect all cables that are plugged into the motherboard.
• D. Reseat the power cable and confirm the outlet is providing energy.

Correct answer: D

Explanation

The correct answer is D, as reseating the power cable and checking the outlet ensures that power is reaching the computer.
