CompTIA A+ 220-1101 (V14) Practice Question

An office employee reports that their computer suddenly displays nothing but a black screen, although the power LED on the monitor and system unit are on. You observe that the monitor status light is indicating a connection, and you hear the computer's fans running. What is the FIRST step you should perform in troubleshooting this problem?

  • Reboot the system to see if the display returns after a restart.

  • Check if the video cable connection is secure between the monitor and the PC.

  • Replace the video card with a known good one to see if the display returns.

  • Replace the computer's power supply unit (PSU) as it may not be delivering enough power to the video card.
