If pressing the power button produces no response, which sequence of checks is most appropriate first?

Answer and explanation

Correct answer: Main power source, cable and Power Supply Unit

When the computer shows no response at all, troubleshooting should begin with the power path: check the wall supply or switch, power cable, connections, and then the power supply unit. This proceeds from simple external causes to the internal component. Option A is correct. Applications, wallpaper, folders, webcam, and speakers cannot be checked meaningfully before the computer receives power and starts.
