Power supply problem Check whether the plug is connected properly and whether the power supply is damaged or has poor contact. Computer poisoning If the laptop shuts down automatically, it is most likely that the computer is infected with a virus. At this time, you need to use anti-virus software to check whether the system has been attacked by Trojans or viruses.
The computer system is poisoned or poisoned. 2 big fans are broken, large temperature difference 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. Solution to laptop automatically shutting down 1. Maybe call a repairman.
Reason 1: Because you haven’t used it for a long time. Solution: Right-click the mouse, select Display Settings, and modify it.
1. The CPU or other hardware is too hot, the memory, the graphics card is incompatible or faulty. The hard disk has bad sectors. Please use the system's built-in functions or software to repair the disk, or format the hard disk, repartition the system, and reinstall the system.
2. Reasons why the computer automatically shuts down:\x0d\x0aPoor heat dissipation of the host, power supply failure, or motherboard failure may cause the computer to automatically shut down or automatically restart repeatedly.
3. Unplug the graphics card, memory, and all hardware on the PCI, and try to boot again. To put down the static electricity, first unplug the power cord, then press and hold the power button for about 30 seconds, then release it, and then try to turn on the computer. Voltage instability may also cause the device to shut down after being turned on.
If it still restarts, it is most likely a system failure. It is recommended to reinstall the system immediately or restore it with one click. After reinstallation, download the latest anti-virus software and upgrade to the latest virus database for scanning and killing. And apply the latest security patches.
It is because the CPU fan is stuck or damaged and the CPU cannot cool down, causing the temperature to be too high. The motherboard activates the self-protection circuit and cuts off the power, so the host stops running. Solution: Clean the dust on the CPU fan and replace it with a new one if it is damaged.
Download the relevant software, test the temperature of the computer hardware, open the case, and check whether the CPU fan and graphics card fan rotate normally. If the problem is found, just replace the CPU fan.
1. It means that the CPU fan is damaged. The fan is damaged, the CPU temperature is too high, and the CPU automatically shuts down for protection! Let's just say that if the CPU fan is broken, the fan needs to be replaced. 4. Check whether the power supply is damaged and whether there is a short circuit or other phenomena in the power supply. Damaged circuits and unstable voltage can cause computer power outages.
2. 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 chassis power supply 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.
3. The reasons why the computer automatically cuts off the power after starting for a while are as follows: the power supply is unstable, the voltage is not enough, or it is broken. The motherboard power supply contact is poor. The CPU has poor thermal conductivity, overheating, the CPU fan does not spin or rotates slowly or even breaks down.
4. The host power supply failed. Due to the leakage of the filter capacitor, poor performance of the transistor, poor performance of the modulation pulse width IC, and the performance degradation of the main drive transformer, there was a sudden power outage and no voltage output, causing the host to stop. operation. Solution: Replace the power supply with a new one.
5. First try to replace the native system to check whether the system is abnormal. If the computer's power supply is unstable, overheating of the motherboard, graphics card or CPU can also cause automatic shutdown. You can try to use the replacement method to determine the problem and replace the corresponding hardware.
6. The power supply itself overcurrents, and the self-restoring fuse circuit operates and cuts off the power output.
: Power supply problem: Insufficient power supply or power failure of the computer may cause the computer to automatically shut down immediately after starting up. 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.
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.
The computer automatically shuts down mainly for 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.
The reason 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, Trojan horse enters, causing startup and shutdown. Remove viruses and Trojans. There is a problem with the RESET switch on the front panel of the chassis.
Reasons why the computer shuts down automatically after being turned on: poor heat dissipation, memory reasons, power supply problems, etc. Poor heat dissipation. The system is overheated due to the influence of weather temperature or insufficient number of revolutions of the CPU fan, which will cause the computer to automatically shut down. You can check whether the system temperature is normal.
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 automatically shut down. 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.
The above is the detailed content of Computer shuts down automatically within a minute of being turned on. For more information, please follow other related articles on the PHP Chinese website!
