What different noises usually mean.
Likely causes
- A fan that’s failing, loose, or clogged with dust
- A hard drive nearing failure, often a clicking sound
- Loose internal components vibrating against the case
What usually helps
- A dust clean and fan check, the most common fix
- Early backup and replacement if a hard drive is failing
- A quick internal inspection to find loose parts
Noise is often an early warning sign, worth checking before it becomes a bigger problem.
