Why are the motherboard and CPU hot 20 minutes before my computer is turned on? If the weather is hot, 10 minutes will automatically shut down. . What's the matter? thank

There must be something wrong with your cooling system. Take it to the maintenance point and have a look.

As for automatic shutdown, it's because your PC is too hot and the computer has a protection system to automatically shut down.

Install a master Lu to monitor the temperature of each hardware, especially the CPU. It is possible that the CPU temperature is too high.

Your computer needs cleaning, or the fan won't work well. This usually happens when the CPU is overheated or overloaded due to the long-term operation of the computer. Excessive dust and abnormal fan operation will lead to poor heat dissipation and overheating of CPU, thus triggering the automatic power-off protection function. If so, it would be nice to solve the heat dissipation problem!

1. Take out the battery of the motherboard, buckle it and discharge it. Objective: To restore the BIOS settings to the default values and eliminate the phenomenon of automatic restart or shutdown of the BIOS hot preset.

2. Clean the dust in the chassis to eliminate the short circuit or poor heat dissipation of the motherboard caused by excessive dust.

3. See if the CPU thermal grease is dry. Silicone grease is used to improve heat dissipation. If there is no silicone grease, it may lead to heat dissipation and the machine will automatically shut down. Note: If there is too much and too thick thermal conductive silicone grease, a thin film will be formed in the middle of the contact surface, which will hinder the direct contact of metals, which is worse than not coating thermal conductive silicone grease.

4. Consider whether the fan size or fan capacity is beyond the reach of high-end computers. First consider the size of the fan (the bigger the better), then consider the power (the bigger the better), and the manufacturer.

5. Other objective reasons, such as high indoor temperature, long-term running of large-scale programs (games) when the computer is turned on, poor heat dissipation of the chassis, poisoning, and frequent CPU utilization rate 100%. Windows Optimizer can be installed, which can not only clean and optimize the system comprehensively, but also detect all the software and hardware information of the system. It can be detected at any time, and compared with the previous information to find problems.
