1.: Power supply problem: Insufficient power supply or power failure of the computer may cause the computer to automatically shut down immediately after starting. 2: CPU radiator failure: If the CPU radiator fails, the CPU temperature may be too high and the computer may automatically shut down immediately after starting.

2. The computer automatically shuts down mainly due to the following reasons: Poor heat dissipation. The system overheats due to the influence of weather temperature or insufficient number of revolutions of the CPU fan, which may cause the computer to automatically shut down. It is recommended to check whether the system temperature is normal. Memory reasons.

3. Insufficient heat dissipation. This may not be because you are blowing the fan on the computer. It may also be that the protection temperature of your CPU is too low. Due to the memory, when the memory is in loose contact with the motherboard slot, it may also cause the computer to shut down automatically. It is recommended to check whether the memory is tightly connected to the motherboard.

4. Generally caused by the following reasons: 1. The computer system is poisoned or infected with malware. 2 The CPU fan is broken. The CPU temperature is too high, overheating protection. 3 The power supply is broken, or new hardware is added and the power supply is insufficient. 4 The graphics card or graphics card fan is broken. 5 The motherboard is broken and the motherboard core is overheated.

5. The reasons why the computer automatically shuts down after being turned on for a while are as follows: poor heat dissipation of the host, power supply failure, or motherboard failure, causing the computer to automatically shut down or automatically restart repeatedly. When viruses and Trojans destroy core components of the system, the running computer automatically shuts down.

6. Reasons why the computer shuts down automatically after it is turned on: Generally speaking, it is caused by hardware. Automatic shutdown is a computer self-protection program to avoid serious damage to the machine. You can try to eliminate: Viruses and Trojans enter, causing startup and shutdown. Remove viruses and Trojans. There is a problem with the RESET switch on the front panel of the chassis.

What causes the computer to shut down automatically and how to solve it

The computer system is poisoned or infected with malicious software. 2 The CPU fan is broken. The CPU temperature is too high, overheating protection. 3 The power supply is broken, or new hardware is added, and the power supply is insufficient. 4 The graphics card or graphics card fan is broken. 5 The motherboard is broken and the motherboard core is overheated.

Excessive dust accumulation. Excessive accumulation of dust on the computer will prevent it from dissipating heat normally. Excessive temperature will burn out the computer hardware, such as CPU, motherboard, etc. The computer will automatically shut down for self-protection. Regularly remove computer dust and re-apply CPU silicone grease to ensure normal computer heat dissipation. Fan failure.

1: Reasons why the computer automatically shuts down Hardware problems: For example, the electric fan of the CPU will be filled with a lot of dust after being used for a long time, which will cause the operation speed to be too slow and the heat dissipation effect is not ideal! This is most likely to cause the computer to crash. Loose memory: Loose memory slots in the chassis can also cause computer downtime.

Reasons why the computer automatically shuts down: Poor heat dissipation of the host, power supply failure, or motherboard failure may cause the computer to automatically shut down or automatically restart repeatedly. (Restarting is an important feature: sometimes it shuts down, sometimes it restarts.) Due to the damage of viruses and Trojans, when the core components of the system are damaged, the running computer may automatically shut down.

The heat dissipation is not enough. This may not be because you are blowing the fan on the computer. It may also be that the protection temperature of your CPU is too low. Due to the memory, when the memory is in loose contact with the motherboard slot, it may also cause the computer to shut down automatically. It is recommended to check whether the memory is tightly connected to the motherboard.

The reason why the computer automatically turns on and off

The reason why the computer automatically shuts down after it is turned on: Generally speaking, it is caused by hardware. Automatic shutdown is a program for computer self-protection to prevent the machine from being damaged. If it is seriously damaged, you can try to eliminate it: viruses and Trojans have entered, causing startup and shutdown. Remove viruses and Trojans. There is a problem with the RESET switch on the front panel of the chassis.

The computer automatically switches on and off generally due to the following reasons: 1. The computer system is poisoned or infected with malware; 2. The CPU fan is broken and the CPU temperature is too high, overheating protection; 3. The power supply is broken, or new hardware is added, and the power supply Insufficient; 4. The graphics card or graphics card fan is broken; 5. The motherboard is broken, and the motherboard core is overheated.

Cause: Caused by poor fan heating of the host. This reason accounts for more than 70%, and the probability of occurrence is usually higher in summer. The main symptoms are that the temperature is too high, there is a problem with the power supply, CPU fan, and there may even be a burning smell. Solution: Spend less time on the computer.

The reason why the computer automatically shuts down: the reason is software virus damage. Soon after the computer was invented, computer viruses also emerged as the times require. When the Internet has become the information artery of today's society, viruses spread more easily, so they also interfere with and destroy our normal work from time to time.

System file damage. System file damage may also cause this kind of problem to the computer, such as KERNEL3DLL under Win2K, Win98FONTS directory If the basic files such as the following fonts are damaged when the system is running, the system will not be able to complete initialization at startup and will force the computer to restart.

Viruses and Trojans enter, causing startup and shutdown. Remove viruses and Trojans. There is a problem with the RESET switch on the front panel of the chassis. Replace the RESET switch. The power supply of the chassis is insufficient, the DC output is impure, and the dynamic response is slow. Replace the power supply with a large power supply. Mains voltage is unstable.

Reasons why the computer automatically shuts down: Poor heat dissipation of the host, power supply failure, or motherboard failure may cause the computer to automatically shut down or automatically restart repeatedly. (Restarting is an important feature: sometimes it shuts down, sometimes it restarts.) Due to the damage of viruses and Trojans, when the core components of the system are damaged, the running computer may automatically shut down.

The mains voltage is unstable. Generally, the working voltage range of the switching power supply for home computers is 170V-240V. When the mains voltage is lower than 170V, the computer will automatically restart or shut down. Because the fluctuations in the mains voltage are sometimes not felt, it is mistakenly thought that the computer has automatically restarted inexplicably.

The heat dissipation is not enough. This may not be because you are blowing the fan on the computer. It may also be that the protection temperature of your CPU is too low. Due to the memory, when the memory is in loose contact with the motherboard slot, it may also cause the computer to shut down automatically. It is recommended to check whether the memory is tightly connected to the motherboard.

The reason why the computer automatically switches on and off is the virus shock wave virus. When the virus attacks, it will also prompt that the system will automatically start after 60 seconds. Trojan horse programs remotely control all activities on your computer, including causing your computer to restart. Solution: Remove viruses, Trojans, or reinstall the system.
