CompTIA A+ Core 1 (220-1101) — Question 109

A technician just finished assembling a new PC for a client. Upon POST, the device presents an unspecified beep code and turns off automatically after five seconds. The technician double-checks the bill of materials for the new build and confirms all items have been installed. Which of the following should the technician do NEXT?

Answer options

• A. Ensure thermal paste is being used on the CPU.
• B. Check to make sure that any video cards have auxiliary power cabling connected.
• C. Verify the header panel connector is properly connected.
• D. Spot-check that the I/O shield for the motherboard is properly installed.

Correct answer: C

Explanation

The correct action is to check that the header panel connector is properly connected, as a loose or incorrect connection can lead to the system failing to boot. While verifying thermal paste, video card power connections, and the I/O shield are important, they are less likely to be the immediate cause of the unspecified beep code and shutdown issue.
