Question

When troubleshooting a motherboard that has no power, which of the following steps would the technician do FIRST?

Options

AUse a multimeter tester.
BUse a post card tester.
CReplace the motherboard with a new one.
DMake sure the computer is plugged in.

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.
