Understanding Computer Troubleshooting
In the computer world, all things computer-related problem called Troubleshooting and problems in the computer of course there's why. On this occasion we will be a little learning to detect problems on your computer, especially that related to Hardware.
Techniques in Troubleshooting
There are two kinds of techniques in detecting problems in the computer, which is a technique Forward and Backward technique. To learn more about these two techniques, it is better we discuss first the definition of each of these techniques.
1.Teknik Forward
As the name implies, in this technique detected all sorts of problems since the beginning of the computer assembled and this technique is usually only used by people who often do the computer dealers computer assembly. In this technique only be done in a simple detection problem and done before the computer is turned on (electrically charged). To simplify please refer to the following example:
• After the computer finished assembled, then carried out checks on all hardware has been installed, for example, examine the relationship of the power supply cord into the power socket on the motherboard.
• For ATX chassis, we check whether the Power Switch cable is properly installed.
2.Teknik Backward
Similar to previous techniques, Backward technique is a technique for detecting errors on a computer after the computer is turned on (electrically charged). Technique is more widely used because in general the problems in the new computer will arise after the "flying hours" his computer had a lot and this is a natural thing. Can we take some examples as follows:
• Floppy Disk that can not read disks properly.
• The computer will not turn on when the power button on the casing is pressed.
After a simple explanation of these two techniques the author will discuss deeper into Backward technique, because for home computer users certainly more of this technique will be used rather than forward engineering. Measurement Analysis
At this stage, the detection problem by measuring the voltage on the component numbers 1 through 3. Use tools like multitester to measure the voltage received or given component.
Example: Measure the voltage received by the Power Supply, then measure the voltage supplied by power supply to other components.
Voice Analysis
At this stage of the detection problem using the code sound (beep) owned by the BIOS and we can hear through your PC speakers. Make sure the PC Speaker cables have been installed properly. Possible location of the problem is on the component number 4 and 5. To facilitate the introduction of the voice code, please refer to the following statement:
• The sound of short beeps once, meaning that the system has done well Boot process.
• short beeps sound 2 times, it means there is a problem in the configuration or settings in the CMOS.
long
• Beep beep 1 time and 1 short time, meaning that there is a problem on the motherboard or DRAM.
• Beep beep 1 time and length 2 times shorter, meaning that there is a problem on the monitor or VGA card.
• Beep beep short length of 1 time and 3 times, meaning that there is a problem on the keyboard.
• Beep beep short length of 1 time and 9 times, meaning that there is a problem in the ROM BIOS.
• Long beep sound continuously, meaning that there is a problem in the DRAM.
• short beep sound continuously, meaning that there is a problem receiving voltage (power).
• In some brands of motherboards will issue a beep several times when the processor temperature is too high (hot).
Note: The beep code above applies to the AWARD BIOS, for other types of BIOS that is likely to have different beep codes.
Analysis Views
At this stage of the detection problem tends to be easier because the location of the problem can be known based on the error message displayed on the monitor. Possible location of the problem is on the component numbers 6 to 9.
Example: When the computer starts Keyboard Error message appears, it is certain the problem lies only on the Keyboard.
Quick Troubleshooting
1.Apabila Recognizing there is a problem and the system still gives a monitor or display message at the beep accompanied by 1 or 2 times, then it is likely the problem lies in the component numbers 6 to 9, ie on the Keyboard, Card I / O, Disk Drives and Diskettes.
2.Apabila occur problem and the system gives beep codes more than 2 times, then it is likely the problem lies in the component number 4 and 5, the RAM, VGA Card and Monitor.
3.Sedangkan for problems that are not accompanied by a message on a monitor or a beep code, most likely the problem lies in the component numbers 1 and 2, namely Power Suplly and motherboard.
With both kinds of techniques in detecting problems in the computer, the course will further enrich our knowledge in the field of computers, so if one day there is a problem on your computer we can examine it before bringing to the service, even if it should bring to the service we already know is the problem, so we're not being lied to by a service person is naughty;)
computer troubleshooting
By understanding the deeper of course it would be easier for us to locate problems in the computer and of course would be more fun if we can fix its own problems. Hopefully a simple discussion about troubleshooting this can be useful.
