'''Computer maintenance''' is the practice of keeping computers in a good state of repair. A computer containing accumulated [[dust]] and [[debris]] may not run properly.
==PC Components==
===Keyboard===
The crumbs, dust, and other particulate that fall between the keys and build up underneath are loosened by spraying pressurized air into the [[Computer keyboard|keyboard]], then removed with a low-pressure vacuum cleaner. A plastic-cleaning agent applied to the surface of the keys with a cloth is used to remove the accumulation of oil and dirt from repeated contact with a user's fingertips. If this is not sufficient for a more severely dirty keyboard, keys are physically removed for more focused individual cleaning, or for better access to the area beneath. Finally, the surface is wiped with a disinfectant.[[File:Pc maintenance Tips.jpg|thumb|Pc maintenance]]
===Monitor===
A [[Computer monitor|monitor]] displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures and It's a part of Output Devices.
===Mouse===
The top surface of the [[Computer mouse|mouse]] is wiped with a plastic cleanser to remove the dirt that accumulates from contact with the hand, as on the keyboard. The bottom surface is also cleaned to ensure that it can slide freely. If it is a [[Computer mouse#Mechanical mice|mechanical mouse]], the trackball is taken out, not only to clean the ball itself, but to scrape dirt from the runners that sense the ball's movement and can become jittery or stuck if impeded by grime.
