Diagnosing a beeping computer

You’re powering up a new computer for the first time. Instead of the normal startup process, the system emits a series of beeps. No message appears on the screen, and no other lights are blinking. What is the most reasonable cause of the problem?

A) The computer has a loose connection or a bad component.

B) There’s no operating system on the boot drive of the new computer.

C) The computer has a bad monitor.

D) The motherboard isn’t receiving any voltage from the power supply.
