As with any device, your computer must be handled with care and serviced periodically. The purpose of the service is, first of all, to clean its elements and blocks from dust and dirt. Through ventilation and other openings in the system unit, ambient air is sucked in, and the dust contained in it settles on the boards and internal devices of the computer. Severe dustiness can lead to undesirable consequences. Therefore, preventive work on cleaning the system unit should become a mandatory procedure for every user.
