Computer is a tool that is quite important at this time, we take one example on the activities office, with the introduction of the computer work can be completed more quickly. As the user or the computer of course we also had problems with the computer. This discrepancy may be due to the basic components of the computer itself that is usually associated with the Software (or software application),
hardware (hardware) or Brain ware (the
computer user).
The Computer Troubleshooting
In the computer world, all problems related to the computer and called Troubleshooting computer problems in the emergence of a reason. On this occasion we will learn to detect a few problems on your computer, especially related to the Hardware.
For problems with the Software should
you do first detection simple as checking the files associated with the Software or specification request (requirement) of the Software. If the problem is quite complicated, you should re-install any software, as will be too complicated to fix a software, while for problems with Brain ware, I can only give advice "resting first deh, he ...."
Troubleshooting techniques in
There are two kinds of techniques in detecting problems in the computer, the technical and engineering Backward Forward. For more about the technique, it's good we first definition of each technique.
1. Forward Engineering
In accordance with the name, then this technique in all kinds of problems detected since the early computer built, and this technique is usually only used by those dealers who frequently perform computer assembly machine. On this technique is only performed detection problems are simple and done before the computer switched on (confluence electricity). To make it easier please see the following example:
§ After the computer finished built, the examination carried out on all the hardware has been installed, for example, check the cable connection from the Power Supply to the power socket on the motherboard.
§ To ATX case, we check whether the Power Switch cable is connected correctly.
§ etc..
2. Backward Engineering
Almost the same as the previous technique, technique is Backward techniques to detect errors on the computer after the computer switched on (confluence electricity). Techniques more commonly used because of the problems in the new computer will arise after the "flying hours" computer is already a lot and this is reasonable. Can we take some examples as follows:
§ Floppy Disk that can not read the floppy with the good.
§ Computer would not turn on when power button is pressed in the casing.
§ etc..
Table detection Problems
After a simple explanation of both techniques is the author will discuss more techniques to Backward, because the home computer users for this technique of course many more techniques will be used rather than Forward. To further simplify the problem in detection on your computer, please see the table below:

At this stage, detection problem with how to measure voltage electrical components on the numbers 1 to 3. Use tools such as multi tester to measure the voltage that is received or given component.
Example: Measure voltage electricity received by the Power Supply, and measure the voltage provided by the Power Supply to other components.
Analysis of Voters
At this stage the problem using the code detection sound (beep), which is owned by the BIOS and we can hear through your PC speakers. Make sure the PC Speaker cables have been installed properly. Possible problems lie in the component number 4 and 5. To facilitate the introduction of sound code, please see the following information:
§ Beep beep a short time, meaning the system has to do with either the Boot.
§ Beep beep 2 short time, meaning there is a problem in the configuration or settings in the CMOS.
§ Beep beep 1 long and short times 1 times, meaning there is a problem on the motherboard or DRAM.
§ Beep beep 1 long and short time 2 time, meaning there is a problem on the monitor or VGA Card.
§ Beep beep 1 long and short-time 3 times, meaning there is a problem on the keyboard.
§ Beep beep 1 long and short times 9 times, this means there is a problem in the ROM BIOS.
§ Beep beep long ongoing, meaning there is a problem in the DRAM.
§ short Beep beep constantly, meaning there is a problem acceptance voltage (power).
§ In some brand motherboard beep sound will issue several times processor when the temperature is too high (hot).
Note: The sound of beep code above apply to the AWARD BIOS, the BIOS for the possibility that other code has a different beep sound.
Analysis Views
At this stage detection issues tend to be more easily fatigued due to the problems can be based on the error message is displayed on a monitor. Possible problems lie in the component numbers 6 to 9.
Example: At the computer switched Keyboard Error message appears, it can be set only on the Keyboard problems.
How to Recognize Fast Troubleshooting
§ When the system is still a problem and give a message on the display monitor, or be accompanied with a beep sound 1 or 2 times, then the problems lie in the component numbers 6 to 9, on the Keyboard, Card I / O, disk drives and floppy disks.
§ If there are problems and provide system beep code sounds more than 2 times, then the problems lie in the component number 4 and 5, the RAM, VGA Card and Monitor.
§ The problem is not accompanied by a message on the monitor or beep code sounds, the most likely location of the problem is in the component numbers 1 and 2, namely Suplly Power and motherboard.
With both types of techniques in detection issue in computer, it will be more enriched our knowledge in the field of computers, so if there is a time problem on your computer, we can first perform the examination to take place before the service, even if the place should be brought to the services we already understand the location of the problem, so we do not the trick by carpenters services practical)
Troubleshooting computer with the understanding that more will be more in the course easier for us to know the problems lie in the computer and of course will be more fun if we can fix your own problems. Hopefully a simple discussion about troubleshooting this can be useful, happy trying and thank you.
Troubleshooting Motherboard
If the processor is considered as the "brain" computer, the motherboard is considered to be "heart" of life on the PC. As a component of a "heavy burden" of damage can only raise a few PC panting of breath.
At the beginning of the computer generation, components such as processors and Ram placed directly on the motherboard can be replaced without changing or more. Such model is called back plane. New design that is modular allowing the replacement of several components attached to the motherboard easily, while providing flexibility available increase opportunities PC technology itself.
However, the ease took always a risk. Similarly, with the motherboard. Since the motherboard is made "shoot the target" key to generate the optimal PC, we are exposed to the complexity, the greater the complexity. Let's point some examples. Increasing the processor needs to make a forceful motherboard design must follow the demands of processors. The need for data transfer requires a faster motherboard design continues to change. Development-development latest technology such as the Fire Ware, USB 2.0, RAID System, Smart Card, Secure Digital, wireless, all gathered in the same area: the motherboard.
Although at this time for all these technologies have not been popular, but to the attractiveness of a product of the motherboard manufacturers are no less resourceful. They roll in providing the space upgrade, without having to include them when it is produced in bulk, to make it still remains economical.
Various types of chipset on the motherboard that a decline measure also more technical support to make the user choose which to be the best. Not yet finished with this one problem, we are also faced with many concerns, how to overcome the problems if safe occur as the heart of the PC motherboard, the problem only a few can make PC-.
Thus the number of options, the key first so that we still do not lose on wilderness is to understand the art of architecture mother board, and provide themselves with the practical ability hold. Here are the steps.
Repair or Replace
The decision to repair is determined by the level of damage that occur on a motherboard. Meanwhile, the replacement step is highly dependent power levels supported by technology, the motherboard or economic ability to spend in your computer goods. The problem is if the motherboard is still new, while we are not able to detect damage or determine the way out? follow the first step before the two decided to buy a new one.
Back to Basics!
• Check all connectors. Of course, this step is necessary to ensure that no one has released the plug or not embedded properly.
• Check all components attached. This is important for detect, whether the processor, RAM, VGA Card is correct or not. Also to ensure that the physical IC-IC in the motherboard is not damaged or detached.
• Check the incoming power source through power supply. To check, first check the supply of electricity from the electricity net, and check the output in the electricity-cable power cable supply using the multimeter. Make sure that the output of each cable is in accordance with that recommended in the manual.
• Review what foreign goods are possible routes motherboard. Cable, screw, dirt, dust can also affect the breath of life motherboards. Interference of this kind, in addition to making the data traffic is interrupted, when the strategic position can cause a short error relationship.
• Check jumpers, jumpers, DIP switch, or pin-pin regulator every feature thoroughly and correctly. Make sure that you refer to the manual do not use the science of recitation. Incorrect settings can make your motherboard did not want to live.
• Check the parts of the motherboard is attached to the casing. Short due to the relationship without the insulator between the casing, the screw fastening the motherboard will make electricity stopped every time the power button is pressed.
The system does not work when the PC graphics card is replaced with on board VGA Card
Problems such as this often happens when users want to upgrade graphics card on the motherboard that has a VGA add on installed. However, on some motherboards, you have to change the settings manually. In fact this will not happen if you know the tips and trick. Usually the problem will occur when the graphics card and add on the plugs you do for the first time. Then the system does not work at all. Does not even issue a beep sound at all.
The first step is to use your back on board VGA. When the entry system is Windows, do the uninstall on board VGA driver that you use. After that, do you restart the system again and then enter the BIOS menu. On this menu, you must turn off or disable the feature-mend VGA on board. After turning off this function out of the BIOS and turn off the system.
The next step is to install the add on graphics card in your AGP slot or PCI slot in accordance with the type of graphics card that you want to use. Once stuck on the right with the appropriate slot, turn on your system again. The system will go back up with the add on graphics card as the primary graphics card. Do not forget to install the latest drivers with the appropriate graphics card is.
The system does not work when the processor is replaced
This incident happened very often when you want to upgrade or downgrade using the processor that has a front-side bus that is different. For example when you are pro-Pentium 533 MHz FSB you change with the pro-FSB 400 MHz, the BIOS while you are still a work-setting system in the 533 MHZ FSB.
So that the system would work again, there are two ways that you can go. The first way is to enter the system BIOS and change the FSB of 133 MHZ is used become 100 MHz. This notes that the system motherboard and processor you can still tolerate the use of the FSB is much higher than that used.
Another way is to clear the CMOS. If this step is already done. Go into your BIOS menu and make sure that the FSB has been used in accordance with the FSB of your processor to work on. This guaranteed effective steps to overcome the problems of this kind.
The system does not work when the DDR memory module is replaced
There are several possibilities that might be an issue why cause problems like this occur. First is the compatibility of the motherboard that is used to install the new memory. The two, namely the memory chip that is used or an issue with the memory type used. Some motherboards require a explicit type of chip used. If not appropriate, the motherboard will not detect the memory that does not result in working system. While some motherboard also does not want dipsangi memory type single side or double side. Once again this problem of compatibility of the motherboard to the memory installed. If the problem is a memory chip, BIOS updates can sometimes be a right solution.
Second possibility is a type of memory that is installed has a CAS latency lower CAS latency memory rather than before, while the latency is still in the BIOS-settings on the CAS-2. the only way is to make clear or reset the BIOS. After that go to the BIOS menu is set to work on the latency of the memory and ability to change in accordance with the memory. The most secure is to change the latency of work on the CL-2, 5.
The system does not work despite all the power has been connected
So this problem can appear because some of the causes. First check if there is the incoming flow of electricity in the motherboard. This is important to make sure there is electricity flowing on the motherboard. On most motherboards, the indications of the electric current that flows are marked with the LED lights up. If the lamp does not light, there can be no electric current that flows.
Second, the possibility of power suplay that is not too good alias does not have the appropriate staff. The way the only change is the power suplay that you have the better.
The cause is probably a third do not terpasangnya graphics card correctly. This is common when you install slapdash add on graphics card. To overcome this, you can improve the position of the installation. Keep the position perpendicular to the motherboard.
The cause of the four do not show that often the key is damaged or the power connection that connects the front panel with the power button on the front of the casing. This causes you can not make up the system even though all installed correctly.
The system suddenly hangs when in overclock
There are several causes for this problem. The cause of the first in the number of components that need working frequency is higher. This happens for example for AGP or PCI installed. To do this, you can go to BIOS and increase the frequency of work. This is the note that if your motherboard supports it.
The cause is the lack of a second voltage that is used. For that, you can also go to the BIOS and the voltage to rise, both on the processor or memory. But how kaerena this risk is highly dependent on the ability and endurance motherboard, processor, memory, and graphics card installed. Kareena This voltage increase will affect the work of some of the attached peripherals.
The system does not work because the hard drive not detected
This problem appears very often on some motherboards. Errors occur not own it in the motherboard, but the data cable that you use. Kesalah usually appear as you use the secondary port and not the primary port even if you do not use a CD-ROM drive or another. On some systems, the motherboard will not detect the use of the data cable because of this kind. Solution that can be done is using the port on the main cable to IDE hard drives sementar secondary to the CD-ROM drive or the other.
The system does not work when the CPU fan cable is not installed
This is common on some motherboards that have a sufficient level of security vessel. On the mother board so that the system will not be willing to work if the cable is not connected to the fan pin is also the appropriate CPU fan. This is meant to ensure that fan working to protect the processor from excessive heat. Well, if you do not install the fan cable on the pin power fan, or even does not install on one of the pin, automated system will not work. The only step taken is to install the CPU fan cable to the appropriate pin.
When booting the system indicate disk fail
This problem appears if you do not have a floppy drive in the BIOS while this feature is enabled. The only way is to enter the BIOS and turn off the features of this one.
The system does not work the three primary graphic adapter replaced
This is common in the motherboard that features the onboard VGA. When will be replaced with the add on graphics card, either PCI or AGP berebasis. When the setting is not installed in accordance with real conditions, the system will not be able to do podići. The only step that can be taken is to make clear the CMOS, or even pull out the CMOS battery if the jumpers to clear the CMOS do not have. This is to force the motherboard back to the default position. After booting can be done, enter the BIOS menu and change the primary graphics adapter setting in accordance with the type of graphics card installed. When you install the AGP-based graphics cards, setting this feature on the AGP add on.
BIOS Password locked
BIOS password is usually used to protect the user on the computer BIOS settings. And if you want to reset the password on the BIOS is not too difficult to mengkoneksikan bateray its CMOS, with a few tricks on the Dos, you can reset the BIOS.
First out of Windows or reboot your computer, start the computer in MS-DOS mode, use the "Command prompt only"
At the C: \> prompt, type:
DEBUG
Press enter. You will see the sign (-) at the DEBUG prompt, then type: o 70 2e
In the DEBUG prompt will be displayed as-o 70 2e. Press enter, type:
o 71 ff
Press enter, type in the last:
Q
Press enter, you will be eating out of the DEBUG prompt and return to the C: \> prompt
Now reboot your PC, press del, and a password to enter the BIOS setup has been done away.
