Teach you how to check and eliminate CPU faults

CPU processor is a PC computer, one of the most important accessories, the operation of various data, processing and other processes are done by the CPU processor. If a computer is compared to a human body, then CPU processor can be regarded as the human brain, control the whole machine parts of the phase to coordinate operation. Due to the high integration of CPU processor, so its reliability is very strong, the correct use of computers in the case of the CPU processor damage to burn the probability is not very high, but also can not exclude man-made causes of the CPU processor damage, burning and so on. Especially in the installation process and overclocking use of the case, very easy to cause CPU damage burned, to our use brought a lot of trouble.

Under normal circumstances, the failure of the CPU processor after the fault is very easy to judge. When the CPU processor is damaged, the most direct fault is that the computer does not boot properly, press the chassis power button after the machine without any reflection, chassis horn No tweet, monitor no signal. If the above phenomenon occurs, it is basically possible to conclude that the processor is having a problem.

So what do we need to pay attention to when installing the CPU? After the CPU processor has failed, which aspects should we check the troubleshooting? In general, we can follow the following steps to judge and exclude.

　　The first thing to note about the installation process is:

First, check the CPU processor is installed in place

The current processor slot design is very standard, the motherboard uses what kind of chip to decide what type of processor to install, high School low-end division is clear, especially the AMD processor division is finer.

CPU is still the main needle-type structure, the installation of the pin on the pin on the design, the wrong direction is not able to properly load the CPU into the slot, in the inspection we focus on whether the installation is in place. At present, AMD uses 754 and 9,392 kinds of products, Intel is the main use of the 478-pin and LGA775 pin interface. The CPU processor slots on the motherboard have positioning measures, if the processor installation is not in place can not be the CPU processor on the motherboard pressure, so the installation must be careful, do not use brute force, especially for 478, 754, 9,393 needle-type interface, the consequences of reckless is the CPU processor to fold the pins , causing the processor to be damaged.

　Second, check the CPU fan operation is normal

CPU because of the high degree of integration, so the calorific value is very large, especially the current processor frequency is very high, 3.0GB is no longer uncommon, so the fan for the stable operation of the CPU has played a crucial role. CPU processors are now in the thermal protection function, after a certain temperature will be shut down, not as the early product because the heat is too large to cause the processor burned, but too high temperature will make the CPU life significantly shorter, and most importantly, the fan installation is not in place or with the processor interface is not tight, Will cause the computer frequently freezes, affects our normal use. Therefore, in addition to the processor to choose a performance advantage of the radiator, but also constantly check the work of the fan, the CPU fan is often checked and maintained. For example, in the case of low temperature, the CPU fan lubricating oil is easy to fail, resulting in a noticeable increase in noise in the work, it is necessary to consider for the CPU fan cleaning and refueling.

In addition, in the hot summer we have to pay special attention to CPU processor heat dissipation, in addition to choose a good performance of the CPU heatsink, a good chassis for the heat is also very important.

Third, check whether the use of overclocking caused by the and various failures

This one is primarily for overclocking users. The current CPU processor frequency is already quite high, can fully meet the needs of our daily life, there is no need to use overclocking. But many friends are still not satisfied, all choose to use the processor overclocking. Of course overclocking after the CPU in the performance of the upgrade is certain, but the stability of the computer and the processor's service life is very harmful. After the overclocking of the CPU on the thermal requirements will be higher, in addition to the higher voltage is very easy to cause the CPU processor burning. In many cases, the machine does not function properly because of the overclocking of the CPU. Therefore, it is recommended that you do not overclocking the processor when it is not necessary.

When there is a normal boot can not enter the operating system, users have to consider whether due to the processor after overclocking caused by the failure, you can enter the motherboard BIOS in the CPU voltage, FSB, etc. to restore the default settings, it may solve the problem.

　　Check that the jumper settings are correct

This is mainly for the old motherboard old processor users, the new motherboard and CPU is generally not the hardware jumper settings. For the use of hardware jumpers of the old motherboard users, set up more complex, a little attention will cause a variety of parameter settings error. Therefore, when the CPU problems first to check the parameters and jumper settings are correct, carefully check the motherboard, read the motherboard instructions, carefully set the parameters.

　　Five, the processor burns, the examination method of the bad press

Open the chassis, remove the CPU fan, after taking out the CPU with the naked eye to see if the processor has been burned, crushed traces. AMD now uses the 754 interface and 939 interface, Intel uses the 478 interface of the processor, the core is relatively delicate, in the installation of the fan will be slightly careless CPU pressure, so the installation must pay attention to moderate strength, the method should be correct, to prevent the use of brute force CPU processor compression.

In addition, the processor is connected through the pins and slots, although the so-called "0 plug" slot, but if the quality of the slot is not good, the CPU in the insertion of the strength is still very large, everyone in the installation to keep the pin and slot balance, in the installation must check the processor's pins are bent phenomenon, do not blindly plug or pull, Otherwise it is easy to damage the pins.

General situation do not often CPU plug, very easy to cause contact with undesirable phenomenon.
