  • Computer, processor, file archiving software and file high volume, initial skills for work with computer.
Instruction
1
The easiest way to determine the faulty processor is to replace it. When you have the opportunity some time to use another one, exactly the same processor, you need to remove the suspect processor from the socket of the motherboard and install another.
2
Health check of CPU could be conducted by testing using special software. Currently, there are many diagnostic programs available for download on the Internet. Downloading a diagnostic program, run it and test the performance of the processor. Moreover, this software allows you to test not only the CPU but also the motherboard, graphics card and other elements of the computer.
3
But most diagnostic programs are paid. If you are looking to test the computer equipment on a professional basis, the purchase of this program you will be inappropriate. There is a free way to test CPU. For this you need any program-archiver (ZIP, RAR) and file large volume of archiving will take several hours. Try to archive the file. If the archiving will take place with errors or after the archiving process the archive file to be unworkable, then this is a clear indication that your processor to work is failing. During backup, the main load is transferred to the processor, and long-term archiving will certainly detect failures.

Advice 4 : How to test a motherboard

The motherboard is needed to establish the reasons for its failure. Having established the cause, you can take steps that will put the health of this very important element in the computer.
How to test a motherboard
Instruction
1
Do the following to test the motherboard. Disconnect power, disconnect from the motherboard all external devices such as a mouse, keyboard, game controllers, etc., it Often happens that because of one poorly assembled device may not work all motherboard.
2
Turn on the power, start the computer. If the motherboard does not start, then the reason is not the fault of any device. If work, turn off the computer and attach one and run it to find out which device is the fault.
3
Check the Reset button to test the motherboard. It happens that the reset button can short. This is due to oxidation of contacts, or any bias. Disconnect the wire from the button and then start the computer. If the motherboard still doesn't work, keep looking for the cause of the fault.
4
Take a voltmeter, check the voltage on the battery the BIOS to understand why is not working motherboard. The battery voltage should not be lower than 2.9 V, and the value of the current should be in the range of 3 to 10 µa. If any of these indicators goes beyond the recommended value, the battery needs to be replaced.
5
Reset CMOS module. This can be done with a special jumper or pulling the BIOS battery and leaving for a few minutes. Return the battery to its former place, try turning on the motherboard. Maybe it's the power supply. Try to check it on another computer. The surest way to determine the efficiency of the motherboard is as follows.
6
Disconnect it from all devices, both internal and external. Leave it on only the CPU and power supply. Then start the computer. If the speaker BIOS at startup beeps, then the motherboard of your personal computer is in working condition.

Advice 5 : How to know whether the processor is operating

In some cases when the computer is booted from a system unit you hear a shrill squeak, which is reproduced by the system speaker (speeker). These sounds are fairly easy to recognize a malfunction or a failure of one of internal devices, including the CPU.
How to know whether the processor is operating
Instruction
1
Diagnosis computer based on the number of signals delivered from the system dynamics. But do not forget that the signals are motherboard, BIOSchips which can be different, therefore, the number of beeps and their frequency depends on the specific model. So listen to the frequency signals and relate them to the tables for each version of the BIOS. Next will be presented the values that relate to failures of CPUs.
2
Award BIOS — the most common model at the moment. With the appearance of high frequency signals (beeping) you must turn off the computer, because this is a sure sign of any problems such as breakage of the cooler. At malfunction of system of cooling of the processor overheating, which can lead to the malfunction of the stone. Frequently, as well as alternating signals only point to problems with the cooling system.
3
AMI BIOS is a second popular model of the internal controller of the motherboard. With this BIOS it's much easier, you need to remember two key figures — 5 and 7. When you see the sound five short signals should be sin in the full malfunction of the Central processor, and at seven the signal is just at the disruption of the virtual component of the processor.
4
AST BIOS — a model that has the smallest spread among modern motherboards. For this type of BIOS definition a faulty device is detected even easier. If you turn the computer on you hear a repetitive single signal, the processor is not functioning properly. When this sound should immediately turn off the computer by holding down the Power button for more than 5 seconds pressed. It is also possible to switch the toggle switch on the back of the system unit (from the PSU).

Advice 6 : How to define, what burned down the maternal

How would the quality nor was the equipment from breakages nobody is insured even when there is a guarantee from the manufacturer. The motherboard is the most important constituent element of the computer system unit. If you find it faulty, because of certain characteristic signs, you will be able to determine whether burned out the motherboard or cause the failure of another part.
How to define, what burned down the maternal
Instruction
1
If you turn the computer on it fails to boot, but the fans are spinning on the Board, check the chip on the motherboard overheating. Remove the system cover and use your finger to touch these circuits. If they become very hot and burn your finger, most likely that is what caused the failure of the motherboard.
2
At the time of turning on the computer listen to all the sounds emanating from him. If the machine is turned off immediately after the start and then not turn on and you hear clicking or crackling is a sign of a short circuit on the motherboard. One of the reasons for such a failure in contact of the conductive element you are interested in details with the system unit.
3
Also on the fault of the motherboard can specify the complete absence of any sounds when the computer starts. If you hear a single signal, but does not turn on the monitor, check the connection to the video card and connect the video card connector on the motherboard. Then remove the memory card from the slot and place it back in place. If the situation does not change after you start the computer, the motherboard should be changed.
4
There are times when the computer will not turn on or off under heavy load, such as when you run "heavy" games. This is one of the indicators of a fault in the CPU power circuit on the motherboard or failure of the current that is applied to it. To confirm or refute these versions remove the motherboard from the system unit. If you see the darkened area, the reason lies in the prolonged overheating of the transistors on the Board. You can replace them, but there is no guarantee that the other elements will work properly. Often all these signs indicate that the motherboard is burned.
