CompTIA A+ Core 1 (220-1201) — Question 115

An employee’s screen keeps flashing. Sometimes the picture goes out and comes back. The employee checks the power cord and confirms the device is plugged in fully. Which of the following should a technician check for first?

Answer options

Correct answer: A

Explanation

The most immediate issue to check is the loose video cable, as it can easily cause a flickering screen and intermittent loss of display. While a failing graphics card, conflicting drivers, and swollen motherboard capacitors could also lead to display problems, they are less likely to be the first cause to investigate compared to a physical connection issue.
