The malfunctioning can be drastically reduced if some simple and steps are followed. The computer user need not to call a computer technician or an IT professional for some minor thing, he can do it himself to keep the machine running. Maintaining your computer properly can help prevent major problems and should be incorporated as part of a regular schedule. Computer maintenance can be broken down into two main areas. Physical and software based maintenance. Physical maintenance: involves cleaning the various internal and external components such as monitor, mouse, printer, system unit, scanners etc. Software maintenance: is the regular virus scanning, spyware/malware scanning and backing up of critical data in the computer. SOLUTION In doing general cleaning, you must not use commercial or household cleaners. Use basic mild solution which is warm water and detergent mixed into a mild solution.

Gently rub over the area to be cleaned. Rinse and repeat it until the dirt is removed. Cleaning each computer devices. Computer: Before embarking on the cleaning unplug the computer from the power source. While you are cleaning your computer visually check external cable connections, untangle the mouse lead and keyboard leads. Monitor: Dust your monitor and the table top. Use the mild solution to clean the monitor SCANNER: Dust and wipe down the exterior of the scanner. Clean glass with the mild solution as earlier explained.
