Troubleshooting

Understanding Troubleshooting

In the computer world, all things computer-related problem called Troubleshooting of problems in the computer and of course there is. On this occasion we will learn todetect a bit of a problem on your computer, especially related to Hardware.
For problems with the Software should you do first as a simple detection checks the files relating to the Software or the specification of the demand (requirements) of theSoftware. If the problem is complex, you should just reinstall the software, because itwould be too complicated to fix a software, while for problems with Brainware, I can only give advice "deh a break, he ...".

Understanding Hardware

Hardware devices (hardware) is one element of a computer system, a tool that can be seen and touched by humans directly, which supports the process of computerization. In the Indonesian language is called by the hardware. Is a device that can take a look andwe can physically touch, such as the input device,
processing device, and outputdevices. This equipment is generally quite sophisticated. He can work on the ordersavailable to it, which is also called the instruction set. With the commands understood by the machine, then the command to do various activities to a machine that is understandable by the machine so the machine can work based on the composition oforders obtained olehnya.terdapat some basic components of a computer must have in order to operate with hardware baik.perangkat a must-have are:

1. monitor: hardware that is useful to visualize the output of the process at the PC,
2. Keyboard: The most important input device used to enter characters, numbers andspecial commands to the computer.
3. Motherboard: place attachment of various computer components. Motherboard as amedium of communication between the CPU, memory, BIOS, CMOS, video devices,sound devices, data storage devices, chipsets, and much more.
4. Memory: used to store data temporarily or long-term watu. RAM is a type of devicewill determine the performance of the computer. The first time the computer starts the process that occurs is the initialization of all devices and further information will be stored in RAM.
5. RAM has many functions, but the important thing is menimpan the execution ofprogram and system hardware drivers that are used.
6. Disk storage is constructed from one or more metal plate arranged horizontally to therotation axis of the plate.

Techniques in Troubleshooting
There are two kinds of techniques in detecting problems in the computer, which is a technique Forward and Backward techniques. To learn more about these two techniques, we should first discuss the definition of each of these techniques.

Forward engineering
As the name implies, this technique is in all sorts of problems detected since the beginning of the computer is assembled and this technique is usually only used by people who often make a computer dealer computer assembly. This technique is only performed on the detection problem in a simple and done before the computer is turned on (powered). To simplify please refer to the following examples:
• After the computer is assembled, the examination of all hardware has been installed, for example, examine the relationship of the Power Supply cable to the power socket on the motherboard.
• For ATX casing, we check if the Power Switch cable is installed correctly.
• and so on.
Backward engineering
Almost the same as the previous technique, Backward technique is a technique to detect errors on a computer after the computer is turned on (powered). The technique is more widely used because in general the problems in the new computer will arise after the "flying hours" computer is a lot and this is a natural thing. We can take a few examples as follows:
• Floppy Disk that can not read the disk properly.
• The computer will not turn on when power button is pressed on the casing.
• and so on.
Table Detection Problem
After a simple explanation of these two techniques I will discuss more deeply into the techniques Backward, because for home computer users of this technique would be used more than Forward engineering. To further facilitate the detection of problems on your computer, please refer to the following table:
Component Detection Problem

1. Power Supply Measurement Analysis
2. Motherboard
3. Speaker
4. RAM Sound Analysis
5. VGA Card + Monitor
6. Keyboard Display Analysis
7. Card I / O
8. Disk Drive
9. Disk
Measurement Analysis
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 that is received or given component.
Example: Measure the voltage received by the Power Supply, and then measure the voltage supplied by the Power Supply to other components.
Sound Analysis
At this stage of the detection problem using the code sound (beep) owned by the BIOS and can be heard through the PC Speaker. 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:
• The sound of a single short beep, it means the system has done a good boot process.
• The sound of a short beep 2 times, meaning there is a problem with the configuration or settings in the CMOS.
• Beep beep one time and short term one time, meaning there is a problem with the Motherboard or DRAM.
• Beep beep one time and the short length of 2 times, meaning there is a problem with the monitor or VGA Card.
• Beep beep one time and a short length of 3 times, meaning there is a problem on the keyboard.
• Beep beep one time and a short length of 9 times, meaning there is a problem in the ROM BIOS.
• The sound of a long continuous beep, it means there is a problem in the DRAM.
• a short beep sounds continuously, meaning that there is a problem receiving voltage (power).
• In some brands will issue Motherboard beep several times when the processor temperature is too high (hot).
• Note: The beep code shall apply to the AWARD BIOS, for other types of BIOS are likely to have different beep codes.
Analysis Display
At this stage tend to be more easy detection of problems due to location of the problem can be determined based on the error message is 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.

How To Recognize Troubleshooting
• If the problem occurs and the system still gives a message on the monitor or beep accompanied by 1 or 2 times, then it is likely the problem lies in the component numbers 6 through 9, which is on the Keyboard, Card I / O, Disk Drive and Floppy disk.
• If the problem occurs and the system gives the beep code more than 2 times, then it is likely the problem lies in the component numbers 4 and 5, ie RAM, VGA Card and Monitor.
• As for the problems that are not accompanied by a message on a monitor or a beep code, most likely the problem lies in the number of components 1 and 2, namely Power suplly and Motherboard.
With both kinds of techniques in the detection of an issue 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 do the first before bringing to the service, even if it should be brought to the service we already understand is the problem, so we are not deceived by a rogue repairman
By understanding the deeper troubleshooting computer 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 can fix your own problems. Hopefully a simple discussion about troubleshooting this can be useful, good luck and thank you.
