Answers
AThe CPU is overheating.
BA POST error, likely related to RAM.
CThe power supply is failing.

Correct answer: B — A POST error, likely related to RAM.
Beep codes are used during the Power-On Self-Test (POST) to indicate hardware failures before video is initialized. 3 short beeps often indicate memory errors.
