Why does the laptop suddenly freeze?

Take Dell G5 and Win10 system as an example. The reasons why the laptop suddenly gets stuck and makes a buzzing sound are as follows:

1. Poor heat dissipation. The system is overheated due to the influence of weather temperature or insufficient rotation of the CPU fan, which may cause the computer to freeze. It is recommended to check whether the system temperature is normal.

2. Memory reasons. When the contact between the memory and the motherboard slot is loose, it may cause the notebook to get stuck or even shut down. It is recommended to check whether the memory is tightly connected to the motherboard, and you can also try changing the slot.

3. It may be caused by CPU failure. Check whether the CPU is overheated and whether the CPU fan frame is stable. If it is damaged or unstable, the CPU fan cannot be pressed, the CPU fan has insufficient cooling capacity, and the CPU If the temperature is too high, the laptop will suddenly freeze and make a buzzing sound.

4. It may be caused by unstable host voltage. The laptop is prone to suddenly getting stuck and making a buzzing sound. Just replace the host.

5. There may be too much dust on the fan, causing the laptop to suddenly get stuck and make a buzzing sound. In this case, the user should first try to clean the dust with a brush and open the main case. Heat dissipation is not good in summer. Good but also prone to problems.

This answer applies to most models of Dell laptops.
