CompTIA A+ Core 1 (220-1001) — Question 229

A technician needs to determine why a PC reboots after a short period of use. The technician installs a hardware monitoring application as part of the troubleshooting process. Which of the following is the MOST likely cause of the issue?

Answer options

Correct answer: B

Explanation

The correct answer is B, as a failing CMOS battery can lead to system instability, including random reboots. The other options, while they can cause issues, are less likely to result in immediate reboots after short usage periods. Bad sectors on the HDD and high storage utilization would typically cause slower performance rather than reboots, while an overutilized power supply would more likely manifest through system crashes or hardware failures.
