Concept:The symptoms shown by the computer are signs that it needs regular upkeep rather than a single quick action.
Explanation:Dust inside the system unit blocks airflow and causes overheating.
Overheating makes the computer slow and causes it to freeze often.
The best way to solve this is to carry out a maintenance procedure.
A proper maintenance procedure includes cleaning the internal parts with safe tools like compressed air.
It also includes checking for malware, removing unnecessary software, and updating the operating system.
Checking hardware connections and reseating components are also part of this procedure.
Hitting the system unit with a blower is not safe and can damage internal parts.
Simply deleting files or changing the computer’s location will not remove dust or fix overheating.
Therefore, the correct action is a full maintenance procedure.
