Explanation
CompTIA's troubleshooting methodology always begins with the most obvious, simplest causes. Before using any diagnostic tools or replacing expensive hardware, a technician must verify the basics - confirming the power cord is securely plugged into both the outlet and the PSU. Using a multimeter (A) or POST card (B) are valid steps but come after confirming physical power connections. Replacing the motherboard (C) is a last resort and would be wasteful if the real issue is simply an unplugged cable.
