Understanding Computer Troubleshooting
In the computer world, all things computer-related problem called Troubleshooting and issues arose in the computer of course there's why. On this occasion we will eventually learn to detect problems on your computer, especially related to Hardware.
For problems with software you should do a simple detection were as the examination of files relating to the Software or the specification of the demand (requirements) of the Software. If the issue is quite complicated, you should re-install any software, because it would be too complicated to fix a software.
1. Forward Technique
As the name implies, this technique is in all sorts of problems are detected early enough and are usually assembled computer technique is only used by people who often do the computer dealers computer assembly. In this technique can only be done in a simple detection problem and done before the computer is turned on (electricity). To simplify please refer to the following example:
1. After the computer is assembled, then the examination on all the hardware has been installed, such as checking the cable connection from the Power Supply to power socket on the motherboard.
2. For ATX casing, we check whether the Power Switch cable is installed correctly.
3. etc2. Backward Technique
Almost the same as the previous techniques, Backward technique is a technique for detecting errors on the computer after the computer is turned on (electricity). The technique is more widely used because in general the problems in the new computer will come after the "flying hours" his computer had a lot and this is a natural thing. Can we take some examples as follows:
1. Floppy Disk that can not read the disk properly.
2. Computer will not turn on when the power button on the casing is pressed.
3. etcAfter a simple explanation of both these techniques the author will discuss more deeply into techniques Backward, because for home computer users certainly more of these techniques will be used rather than forward engineering. To further facilitate the detection of problems on your computer, please refer to the following table:
No. | Component | Problem Detections |
1 | Power Supply | Measurement Analysis |
2 | Motherboard | |
3 | Speaker | |
4 | RAM | Voice Analysis |
5 | VGA Card + Monitor | |
6 | Keyboard | Display Analysis |
7 | Card I/O | |
8 | Disk Drive | |
9 | Disket |
At this stage, the detection problem by measuring the voltage on the component numbers 1 through 3. Use tools such as multitester to measure the voltage received or given component.
Example: Measure the voltage of electricity received by the Power Supply, then measure the voltage supplied by the Power Supply to the other components.
Example: Measure the voltage of electricity received by the Power Supply, then measure the voltage supplied by the Power Supply to the 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 cable is installed properly. Possible location of the problem is in the component numbers 4 and 5. To facilitate the introduction of the sound code, please refer to the following statement:
1. The sound of short beeps once, which means the system has done a good boot process.
2. Short Beep beep 2 times, it means there is a problem in the configuration or settings in the CMOS.
3. Beep beep 1 time long and short a time, meaning there is a problem on the motherboard or DRAM.
4. Beep beep and a short length of 1 time 2 times, meaning there is a problem on the monitor or VGA card. 5. Beep beep long one short times and 3 times, meaning there is a problem on the keyboard.
6. Beep beep long one short times and 9 times, meaning there is a problem in the ROM BIOS.
7. long beep sound continuously, meaning that there is a problem in the DRAM.
8. short beep sound continuously, meaning that there is a problem receiving the voltage (power).
9. In some brand 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, the BIOS for the other types may have different beep codes.
Display Analysis
At this stage detection of problems tend to be easier because the location of the problem can be determined based on the error messages are displayed on the monitor. Possible location of the problem is in the component numbers 6 through 9.
Example: When the computer starts Keyboard Error message appears, it can be ascertained only on the Keyboard layout problems.
Example: When the computer starts Keyboard Error message appears, it can be ascertained only on the Keyboard layout problems.
1. If the problem occurs and the system still gives a message on the monitor or a 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 Drive and Diskette.
2. If the problem occurs and the system gives beep codes more than 2 times, then it is likely the problem lies in the component numbers 4 and 5, the RAM, VGA Card and Monitor.
3. As for the problems that are not accompanied by a message on the monitor or a beep code, most likely location of the problem is in the component numbers 1 and 2, namely Power suplly and motherboard.
With both techniques in the detection issue with 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 do the inspection first before bringing to the service, even if it should bring to the service we have understand is the problem, so we are not deceived by the repairmen that naughty;)
With a better understanding in troubleshooting computers would be more easier for us to know the location of the problem in the computer and of course it would be nice if we could fix their own problems. Hopefully a simple discussion about troubleshooting this can be useful, good luck and thank you.
