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.
Dust and debris will accumulate as a result of air cooling. Any filters used to mitigate this need regular service and changes. If the cooling system is not filtered then regular computer cleaning may prevent short circuits and overheating.

How to Refresh and Maintain your PC's performance - Computers, just like cars, bikes, and girlfriends, need regular maintenance in order to perform at their best. Here's some tips to make sure your PC isn't getting clogged up with rubbish/garbage/.t...
Keyboard
The crumbs, dust, and other particulate that fall between the keys and build up underneath are loosened by spraying pressurized air into the 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.
Monitor
A 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. There are two basic types of monitors: CRT (cathode ray tube) monitors and LCD (liquid crystal display) monitors. Both types produce sharp images, but LCD monitors have the advantage of being much thinner and lighter. CRT monitors, however, are generally more affordable.
Fingerprints, water spots, and dust are removed from the screen with a cleaning wipe specialized for the screen type (CRT, LCD, etc.). A general plastic-cleaning agent is used on the outer casing, which requires a less gentle cleanser but may need more focused attention to unusual buildups of dust, grime, pen marks, etc. idiosyncratic to the user and environment.
Mouse
The top surface of the 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 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.
Tower/desktop unit
Internal components accumulate dust brought in by the airflow maintained by fans to keep the PC from overheating. A soft brush may remove loose dirt; the remainder is dislodged with compressed air and removed with a low-pressure vacuum. The case is wiped down with a cleaning agent. A pressurized blower or gas duster can remove dust that cannot be reached with a brush.
Data
Backups
Important data stored on computers may be copied and archived securely so that, in the event of failure, the data and systems may be reconstructed. When major maintenance such as patching is performed, a backup is recommended as the first step in case the update fails and reversion is required.
Disk cleanup may be performed as regular maintenance to remove these. Files may become fragmented and so slow the performance of the computer. Disk defragmentation may be performed to combine these fragments and so improve performance.
Legal issues
In the U.S.A, the Digital Millennium Copyright Act specifically exempts computer-maintenance activities, so copies of copyright files may be made in the course of maintenance provided that they are destroyed afterwards.
Software
Operating system
Operating-system files such as the Windows registry may require maintenance. A utility such as a registry cleaner may be used for this. Also inbuilt Disk defragmenter will also help.
Software updates
Software packages and operating systems may require regular updates to correct software bugs and to address security weaknesses.
Security
Maintaining security involves vulnerability management and installation and proper operation of antivirus software.
