2. What are the common computer failures? How to solve?

1. CPU temperature is too high leading to crash: This problem is most likely caused by CPU overclocking, abnormal fan operation, poor heat dissipation installation, or uneven application of heat dissipation silicone grease on the CPU base. The editor here recommends disassembling the case and checking whether the fan rotates normally. If not, it is recommended to replace it with a fan with better performance. Then check whether the heat sink is firmly installed and in close contact with the CPU. Also check whether the CPU surface is coated with thermal grease or whether it is evenly applied. Finally, if the user has overclocked the CPU before, it is best to lower the frequency or do a good job of cooling the CPU. If this operation is not performed, the CPU will easily be burned!

2. The fan in the computer case is noisy: A friend sent a private message to the editor before asking what should I do if the computer case is noisy? In fact, if the wind direction noise of the chassis is loud, it is most likely caused by long-term use and lack of lubricating oil to the fan, which in turn causes the fan bearings to dry up and cause high friction. To solve this problem, we only need to add some lubricant to the fan bearing.

3. The computer automatically shuts down or restarts: The computer automatically shuts down or restarts for unknown reasons? Of course, it is possible that the CPU temperature is too high, the power supply fails, the motherboard temperature is too high and the automatic protection function or viruses are enabled, etc. When this fault occurs, we must first confirm whether the CPU's heat dissipation is normal, open the case and check whether the fan blades are operating normally, and then enter the BIOS to check the fan speed and CPU temperature. If there is a problem with the fan, we need to maintain it. If the CPU has been overclocked, it is recommended to restore it to its original frequency or replace it with a high-power fan. There is another situation. If the computer has been used for a long time, the power supply may be aged or damaged. If this is the case, it is recommended to replace the power supply with a new one as soon as possible to avoid burning out other hardware.

4. The impact of BIOS settings on CPU overclocking: The most common danger of CPU overclocking in BIOS settings is heat. When computer components are run higher than rated parameters, it will generate more heat. If the heat dissipation is insufficient, the system will It may overheat, causing the computer to malfunction. In the "Frequency and Voltage Settings" option in the BIOS, there is an option called "Spread Spectrum". Setting it to "Enabled" can disable overclocking.

5. Turning off the second-level cache causes the computer to run too slowly: When the CPU reads data, it must read from the cache, which greatly slows down the speed of the CPU reading data. In the BIOS settings, we can check whether the CPU Level2 Cache option is set to Disabled. If so, change it to Enable, save and exit to solve the problem.
