Therefore, the preventive maintenance of the system of the computer system is based on;

1) The computer location, such as the presence of dust in the environment, that can clog the circuit board of the system, or exposure to liquid that require ensuring protective covering of parts, or the high temperatures, that may require extra cooling through the use of fans

2) The computer usage; Including how the computer is used, either continuously, or once in a while, the traffic the computer is experiencing, the presence of temporary files, and malicious programs, that require removal.
