When the computer is unstable, when the power is turned on after power-on, if the power, memory, and software viruses are excluded, the CPU has problems after the power supply, memory, and software viruses cause the fault. Although the fault performance caused by the CPU is a variety of diversified, it is induced by frequent crash. The operating frequency displayed by the power-on self-test is repeated. Due to overclocking, there is no response after the system is powered up. the way. Of course, the way to deal with it is not the same, and we will introduce them separately:
1. Frequent crash
This kind of fault is relatively common. The main reason is generally caused by the poor heat dissipation system, the CPU is in contact with the socket, and the BIOS is caused by the CPU high temperature alarm setting error. The countermeasure is mainly carried out around the CPU heat dissipation, the connector is reliable and check the BIOS settings. For example: Check if the fan is operating normally (if necessary, the fan can be replaced with a fan), check whether the heat sink and the CPU contact are good, the heat-conductive silicone is applied is uniform, and the contact of the CPU check the pin and the socket is reliable. , Enter the BIOS setting to adjust the temperature protection point.
2. The operating frequency displayed by the boot self-test is not normal
The specific manifestation is a prompt of the CPU operating frequency after the power is turned on, and the "Defaults CMOS Setup loaded" prompts, after resetting the CPU parameters in the CMOS, the system can resume normal display, but the fault will appear again. This is related to the corresponding circuit of the CMOS battery or motherboard. In the case of this failure, you can follow the principle of easy-to-demo repair, first measuring the voltage of the motherboard battery, if the voltage value is less than 3 volts, consider replacing the CMOS battery. If there is no battery replacement battery, the fault has occurred again, and the components of the motherboard CMOS power supply loop are leakage, and the motherboard will be repaired.
3. Unable to turn over overclocking
After excessive overclocking, when the computer starts, the cooling fan is rotated normally, and the hard disk light is only looked up, and the display is not reactive, and the display also maintains the failure of the standby state. Since it is no longer possible to enter the BIOS setting option, it will not be able to drop the CPU. There are two ways to process this situation:
(1) Turn on the chassis and find the jumper to the CMOS discharge (generally arranged near the button battery), set it in the "CMOS discharge" position or ignore the battery, wait a few minutes, Reset the jumper or battery and restart your computer.
(2) Nowadays, most of the new motherboards have special recovery measures that have failed failure. For example: You can press and hold the INSERT button while booting. At this time, it will automatically enter the BIOS setting option after the system is started. In some more advanced motherboards, the default running frequency of "self-recovery" CPU can be active after overclocking failure. Therefore, for ordinary readers who are kerge overclocking and lack of actual operation experience, choose the "Magic Overclock", "Maguate Failed", "overclocking failure automatic recovery", will make the overclocking CPU work unusually unusually unusual Easy.
4. System power is not reacted
The "replacement method" can generally be used in this fault to determine the specific part of the fault. If the motherboard is eliminated, the power is throwing the possibility of the fault, it can be determined that the problem with the CPU is mostly damaged by internal circuitry. If so, only can be solved by replacing the CPU.
Tip: Some people think that the higher the speed of the CPU cooling fan, the better the heat dissipation, in fact, this understanding is a one-sided. In fact, the heat dissipation capacity of the fan is, the angle, the effective exhaust area, and the exhaust volume have direct contact, and the speed can improve the exhaust amount, but will result in an increase in noise, shortening the life. . Therefore, it should be considered when selecting a cooling fan.
