Maintenance issues
  • The performance of a hard disk starts to slow and printer problems may start to occur.
  • The keyboard and the mouse can become sluggish and the monitor may not work properly.
  • Managing computer cables is an overlooked problems when maintaining a computer system.
hardware maintenance
Hardware maintenance
  • One of the best ways to cut down on computer repair is thought preventative maintenance performed on a regular schedule. As general rule you should clean computer every 3-6 months.
  • Keyboard and mouse
  • You should check and clean the keyboard periodically dirt, dust, hair, food particles can accumulate causing the keys to jam or otherwise malfunction. If you spill a liquid onto the keyboard turn off the computer immediately disconnect the keyboard spray it with water to clean it turn it upside down and shake to remove the liquid.

preventative maintenance
Preventative maintenance

  • Disk defragmentation: as you add and delete files on the computer hard disk when the computer is new the operating system such as window vista writes the file data in a set of side by side clusters. As the drive begins to become cluttered and space becomes limited windows divides the data for newly crated files into sectors
  • Recycle bin: the windows recycle bin is a holding area for files and folders before their final deletion from a storage device.
  • temporary files: various application programs such as Microsoft office suite create temporary files this action is used for the following three reasons, to free memory for other programs, to act ad a safety net to prevent data loss, for printing.
