Question

A school computer lab has 20 identical computers. Several systems show: computer powers on (fans spin and lights turn on), but nothing appears on the monitor and no startup sound is heard. Monitors and cables are working fine. A technician swaps the OS drive from a working computer into a faulty system but the problem still persists. What is the most likely cause?

1. A. The operating system is corrupted and needs to be reinstalled
2. B. The graphics driver is outdated and incompatible with the monitor
3. C. A hardware failure in a core internal component (Correct answer)
4. D. The monitor resolution settings are unsupported by the operating system

Correct Answer

Option C — A hardware failure in a core internal component

Detailed Solution & Explanation

The correct answer is A hardware failure in a core internal component.

Key Points

• Since the OS drive from a working system still fails, the OS is not the cause.
• The issue must be hardware - likely RAM, GPU, or motherboard failure.
