Hard disk (3:0) not found.

Refer to the exhibit. A computer displays this error during startup. Which component is most likely the cause of the issue?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Hard drive

(Hard drive) is correct because the error explicitly states that the hard disk is not found, indicating a problem with the storage device or its connection. Option A (RAM) would typically cause beep codes or a blank screen, not a boot device error. Option B (CPU) failure usually results in no power or beeps. Option D (Power supply) issues often lead to no power or intermittent shutdowns, not a specific hard disk error.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    RAM

    Why it's wrong here

    Faulty RAM typically causes beep codes, system crashes, or failure to POST, not a 'boot device not found' error.

  • ✗

    Power supply

    Why it's wrong here

    A failing power supply may cause random shutdowns or failure to power on, but not a specific hard disk not found error.

  • ✓

    Hard drive

    Why this is correct

    The error message directly indicates the hard disk is not detected, pointing to a failed drive, loose cable, or incorrect BIOS settings.

  • ✗

    CPU

    Why it's wrong here

    A failed CPU usually results in no display or beep codes; it does not generate a hard disk error message.
