Why does my computer suddenly shut down on its own?

It may be a problem with the monitor, try plugging in a good monitor, if this still happens.

It may be a problem with heat dissipation, open the case, clean the dust inside, clean the slot with a brush, wipe the metal copper sheet with an eraser, and reinstall the system if it doesn't work.

I've had this situation before, it may be that the memory module is loose, take out the memory module, wipe the metal copper sheet with an eraser, and then change the socket to plug it, if it still doesn't work, it means that there is a problem with the memory module.

If yes. Okay. Suddenly the screen went black. If the host is still working, it means that the graphics card is broken, and the graphics card is replaced.

Restart it to see if this situation continues, if so, it may be caused by malware modifying the computer registry and sending a shutdown command to the machine. Unplug the network cable and carry out a thorough antivirus.

Is the host still working? It should be a problem with the display.

I'm having a problem with the key opening of the host panel, you try to pull out the prower cable of the host panel.

Turn on the machine with a lit method.

This kind of problem can only be solved by elimination, a total of 4 places, one is the power supply, the second is the network card, three memory, four motherboards, the power supply is the most common, because the power supply is not enough for a moment and suddenly power failure, if this problem is not solved, the associated problem is to destroy the hard disk, so if you have the ability, change the power supply first to see if the power is off.

The network card is also a problem found in the recent period, when the network card transmits data, it will also cause power failure or restart when encountering technical problems, so unplug the network card when detecting, and then see if the power is still off and restarted.

This problem can also occur in memory, one is caused by static electricity, and the other is that there is a problem with the memory itself, which will lose power immediately after running, after an error.

The probability of the motherboard is the smallest, under normal circumstances, only the capacitor will break, but if you don't use the computer much, the capacitor should not break too quickly, basically 10 capacitors can be used for more than 5-6 years.

You try this, maybe it will solve your problem, maybe there is still I don't know.

Problems with the graphics card or monitor.

Check to see if it's the graphics card!.

If not!

You're going to find someone to fix your computer!.

The world of notebooks is colorful, and there are various types of notebooks for people with different orientations. At the same time,The problem of the notebook is also strange,What problems also have,Yesterday,The company encountered two computers in normal use at the same time suddenly shut down the problem,I think it's very interesting,Write it out and share it with you。

The first is the P-450 of the gateway, and the system is win2000 server; The fault is: when it is in normal use, it will suddenly shut down automatically after about 5-20 minutes of operation. At first, it was estimated that it was the "Shockwave" virus that was very popular some time ago, but after checking with the Rising antivirus software that specializes in killing "Shockwave", it was found that there was no virus.

What's going on here? CPU overheating? However, after running for such a short time, even if it is hot, it will not overheat and automatically shut down, and you will not feel that the temperature is high when you touch the heat vent with your hand.

After a few iterations, an attentive engineer found that when running a program, such as work, it would automatically shut down for a shorter period of time, but if no software was running or when it was on standby, then the automatic shutdown time would be extended. It seems that the problem is with the CPU. Dismantling the book and looking at it, it was fixed and found that half of the screws of the heat dissipation system were missing, it seems that the CPU should be in poor contact with the heat sink caused by the CPU overheating and automatically shut down.

Remove the heat dissipation system, coat the heat sink with silicone, and attach the fixing screws. Power on, everything works fine.

Reason for automatic shutdown of computer black screen:

1.Viruses in your computer.

2.It is enabled to automatically shut down and restart when the computer encounters a serious error3A critical memory error is causing the system to crash (software issue).

4.Malicious program or **.

Phenomenon: During the normal operation of the computer, the system suddenly and automatically shuts down or restarts the system.

Phenomenon analysis: Today's motherboards have a temperature monitoring function for the CPU, once the CPU temperature is too high, exceeding the temperature set in the motherboard BIOS, the motherboard will automatically cut off the power supply to protect the relevant hardware. On the other hand, power management and virus software in the system can also cause this phenomenon to occur.

Laptop automatically shuts down and powers off; The common reasons are: first, caused by poor heat dissipation, it is enough to disassemble the machine to clean the fan or replace the fan; Second, the BGA (north-south bridge, graphics card) packaging chip on the motherboard is damaged by virtual soldering, which needs to be repaired and solved. It is recommended that you send it for repair and testing.

I'll help you in Beijing.

If you are not in Beijing, it is recommended that you find a reputable and skilled repairer to help you overhaul.

This situation is generally a fan problem, repair the fan will be fine, in Beijing can help you.

Find a professional, suddenly the power is off and shut down Just like the upstairs said, the first shift is ...... hardware may have problems

The hardware is too hot.

The power bank is dead.

The system rebooted with an error.

This problem is more complicated, which requires professionals to test it, or send it for repair. There is also your computer is powered off at once, or like that normal shutdown, if it is a normal shutdown, then it is a software problem, if the power is off is a hardware problem, or reinstall the system first, if the system is not reinstalled It is a hardware problem, I hope it will help you.

If you are in Beijing, our company can provide you with free testing.

Let's see if the fan is spinning.
