220-1101 Question 402
Single answerClicking soundsA user reports that their desktop has become very slow and occasionally freezes when opening large files. During startup and again when accessing data, you hear a repetitive clicking sound coming from inside the case near the 3.5-inch drive bay. What is the MOST appropriate next step for the technician to take?
- A
Back up the user's data immediately and plan to replace the hard drive
- B
Run a disk defragmentation utility to reorganize the file system
- C
Increase the system's RAM because insufficient memory often causes clicking noises
- D
Reseat the video card because GPU initialization can sound like a drive clicking
Show answer and explanation
Correct answer: A
Explanation
In A+ Core 1 troubleshooting, repetitive clicking from a traditional spinning hard disk is a classic sign of mechanical drive failure, often associated with read/write head or actuator problems. When this symptom appears together with freezes, slow file access, or startup issues, the technician should prioritize data preservation over performance optimization steps. Best practice is to back up important data immediately if the drive is still accessible, verify the drive's status if possible using vendor diagnostics or S.M.A.R.T. information, and replace the disk. Routine maintenance tasks such as defragmentation are inappropriate when a drive shows signs of imminent mechanical failure because they increase disk activity and risk data loss.
- A. Correct.
Correct. Repetitive clicking from a mechanical hard disk, especially combined with slow performance, freezes, and file access problems, strongly suggests a failing HDD. The best immediate action is to protect the data by backing it up as soon as possible and then replace the drive. This matches standard troubleshooting practice: identify likely hardware failure, preserve data, and replace the failing component.
- B. Incorrect.
Incorrect. Defragmentation is not an appropriate first response to a drive making clicking sounds. On a failing HDD, additional read/write activity can worsen the problem and increase the chance of total failure before the data is secured. A candidate might choose this because slow performance can sometimes be helped by maintenance tasks, but the clicking noise points to hardware failure, not simple fragmentation.
- C. Incorrect.
Incorrect. Low RAM can cause poor performance, excessive paging, and slow application response, but it does not cause a mechanical clicking noise from the drive bay. Someone might pick this because the system is slow and freezing, but the physical sound is the key clue indicating a storage device issue.
- D. Incorrect.
Incorrect. A video card problem can cause display issues, boot problems, or artifacting, but it would not typically produce repetitive clicking from the hard drive area during file access. This distractor reflects a misunderstanding of matching the symptom location and behavior to the correct component.
