Definitely, incorrect use of your computer as well as other equipment related to it, although indirectly, may still damage your health. These equipments may expose you to increased health risks.

Perhaps that is the reason why there is a work place regulation in force that affects everyone working with and using computer and VDUs. This is to protect the health and safety of these people from health risks such as eye strain, fatigue, etc.

Although it had been said that computer use will not directly and seriously damage your eyes or vision there are more computer users blaming computers for fatigue, double or blurred vision, drying and tearing of their eyes, problems in focusing, frequent blinking, squinting, head aches and eye strain. This collection of symptoms that is said to be caused by prolonged use of computers is called Computer Vision Syndrome.

The reason why these symptoms appeared related to computer use is simple. The human brain reacts differently to text found on the computer screen and on printed materials.

Actually, the symptoms are not directly caused by the computer monitor. Such conditions as intense brightness or dimness may cause the symptoms.

Also, the idea that the Ultra violate radiation put out by the computer screen causes the symptoms is not at all true because the radiation of computer screen is minimal.

One way to know their system problem is trouble shooting. Troubleshooting is the process of narrowing down the possible reasons for a failure until you left with the cause. Effective troubleshooting follows a systematic approach in solving a problem. It requires that you:

  1. Know The System – this mean that understands the detailed operation of the system by knowing the supposed sequence of events and what component causes each event. It requires by studying the block diagram, the schematic diagram, and wiring diagram.
  2. Investigate the Symptoms of Failure – the symptoms of failure often indicate which sections of the machine are in the real trouble.
  3. List Probable Cause of Trouble – base on what you know and the clues you have uncovered, list the probable or likely causes of trouble. Usually this can be done in your head. But if a machine is complicated, it can help to list with pencil and paper.
  4. Eliminate Possibilities Systematic – this means performing test on the machine in a logical order. Usually, you are trying to eliminate a whole group of possibilities with one test, narrowing down the choices as quickly as possible until you are left with the actual cause of trouble.
  5. Determine the root cause of trouble – getting the equipment run again is often not the end of the troubleshooting procedure. You may be able to discover why the trouble happened, and do something to keep it from again.

Simple ways to set a troubleshooting list but can barely help as a simple guide.
