COMPUTER TROUBLE SHOOTING

Computer Trouble Shooting

First Page

Troubleshooting in computer and their others peripherals is a complex process. There can be many reasons for one fault in this by identifying these reasons, this process becomes much easier and the problem can be easily removed. Some things to keep in mind while shooting trouble.

1) Do not handle any device rough.

2) When a device is not opened or inserted, it should not be forced, but to find out the reason.

3) When opening the device or cover, each screw received should be kept in one place.

4) Each of screw should be placed in its place when turning of the system or other device.

5) Before opening any system, this device should be thoroughly inspected.

6) There are fewer screw and more clips in computer, printer, device, so the technique of opening them should be looked at first.

7) Do not open or close any device with power.

8) The device must discharge itself by touching the wall etc., before touching the electronic circuit.

9) The device should not be operate with a screw driver or hand in the ON condition.

10) While replacing any components, the device of old value should be mixed together.

11) Sophisticated devices should not be touched repeatedly by hand.

Faults can be of two types, solid and intermittent.

Solid fault: this type of fault is called a permanent fault. Any work gets completed by them.

Intermittent fault: these types of fault come intermittently in the system. Some times the system start working fine and sometime is faulty.

Hardware fault: the reason for system failure is some hardware device like RAM, HDD, FDD, interface card, SMPS etc., in this case, the faulty device needs to be taken.

Software fault: if the reason for the system not working now is software, then there is no need to open the system but it can be corrected only by software tools and diagnostic software. Computer trouble shooting is divided into four main parts. At this time, on the basis of systematic trouble shooting, any system defect can be detected and rectified. It following:

1) Symptoms observation

2) Symptoms analysis

3) Fault diagnosis

4) Fault rectification

Symptoms observation: To rectify a system failure, one should first look carefully at the symptom caused by the fault. Most fault are detected from the outside of the system itself. it should not jump to any conclusion without observation.

Symptom analysis: the system symptoms should observed or analyzed to see if the problem could be from any section of the system. the problem is hardware by doing system analysis from software`s memory device or power supply, we can start the process of repair in the right section.

Fault diagnosis: the cause and department of the fault can be ascertained by one time symptom observation. The process of locating and repairing the faulty device should begin. There should be absolutely no rough handling while making fault diagnosis.

Fault rectification: after the diagnosis, if you are replacing the faulty device, then the matching of the device must be kept in mind and the value and capacity of the new device should be combined. A computer is such a device that it dose not work just by replacing the new divide, but it also needs to be configured by the bios software. After replacing the device, meet these requirements as well.
