CompTIA A+ Core 1 (220-1001) — Question 327

A user replaced a failed CPU on a desktop PC. During post-repair testing, the PC shut off shortly after a successful POST and before the OS could fully load. The user calls a technician for assistance. Which of the following should the technician perform FIRST?

Answer options

• A. Ensure thermal paste was applied
• B. Check the motherboard for distended capacitors
• C. Verify processor compatibility with the motherboard
• D. Look for BIOS updates from the manufacturer

Correct answer: C

Explanation

The technician should first verify processor compatibility with the motherboard, as an incompatible CPU can lead to immediate shutdowns after POST. While ensuring thermal paste is applied and checking for hardware issues are important, they should follow the compatibility check. BIOS updates are less likely to be the cause of the issue compared to compatibility matters.
