CompTIA A+ Core 1 (220-1201) — Question 10

A user reports that their desktop PC does not turn on. Which of the following components would most likely cause the issue?

Answer options

• A. PSU
• B. GPU
• C. RAM
• D. CPU

Correct answer: A

Explanation

The Power Supply Unit (PSU) is the most common cause of a desktop PC not turning on, as it provides the necessary power to all components. While the GPU, RAM, and CPU can also cause issues, they typically result in other symptoms such as failure to boot or display problems rather than a complete lack of power.
