What s going on with the computer shutting down or standby abruptly too often?

May be 1. Poor heat dissipation, it is important that the CPU is well ventilated. Working too long can also lead to:

CPU heat dissipation problems are also an important cause of computer failures. 2。There is too much dust inside the case.

Please clean it in time and keep the inside dry and clean. 3。It may be that the memory module is loose, and it should be pulled out to check whether it is damaged.

Aging or improper use of hard drives is also one of the reasons. Professional software can be used to troubleshoot the problem, and if the damage is serious, the hard disk can only be repaired or replaced. 4。

There are compatibility issues with hardware and software. 5。The memory footprint is too large, ending unnecessary programs or the memory configuration is low.

5。The hard disk has logical or physical bad sectors 6. Viruses are planted to kill and kill software.

7。If there are too many junk files or fragmented files, it is recommended that you clean up the system junk regularly. You can also restore the system, which is convenient and easy.

Reasons for automatic shutdown:

First, press F8 on boot, and then enter the correct configuration for the last time, because it may be that the software is installed that causes incompatibility.

Second, apply some silica gel on the CPU, because the time is up, and the silica gel on the CPU has dried into powder due to temperature. This does not dissipate heat well, which will lead to this problem. It is best to clean the fan of the lower CPU.

Third, virus reasons, or system files are corrupted. Restore the mirror or redo the system four, caused by the memory, change the root memory to see.

The automatic shutdown of the computer is mainly caused by the following reasons:

1.Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

3.Power issues. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.

4.Software factors. Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down.

5.Problems with hardware compatibility. Chances like you are that are the problem.

Is it a laptop or a desktop?。。 If it's a notebook, will the temperature be high when it shuts down automatically?。。 If so, it may be caused by dust accumulation in the fan. It is recommended that the landlord clean, or replace the fan! The fan is about 100 yuan!!

But still wait for the landlord to inform the specific problem!

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated and whether the CPU fan holder is stable, if it is broken.

Or it is unstable, the CPU fan cannot be suppressed, the CPU fan has insufficient heat dissipation capacity, and the CPU temperature is too high, and the motherboard's automatic protection function will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to use 360 Antivirus 360 Security Guard to repair it in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

The temperature is too high.

Exceed the temperature set in the BIOS.

2.The power supply is in poor contact or unstable or aging.

3.Poor memory contact.

7.There's a lot of dust.

Clear it up. 5.The computer has a virus.

Check and kill with 360.

When the temperature of the CPU or graphics card is overheated, it will affect the running speed of the system and cause the computer to shut down, so check whether the cooling fan of the CPU and graphics card is running normally or that there is too much dust in the radiator that affects the heat dissipation ability, and there is a possibility that the system may be infected with viruses and Trojans.

It may be that your computer has become someone else's broiler, and others can control it however they want, and it is actually malicious**、。。

The more common thing is that the heat dissipation of the machine is too poor.

Check to see if there is obvious dust in the vents around the machine, whether there is dust on the CPU inside the case, whether there is more dust in the power supply vents, and whether the power supply fan is normal or not. If there is dust, clean it up.

If you have a problem with heat, you can also open the case and run it until there is a problem, and immediately use your hands to feel the CPU heat sink, graphics card heat sink, and North Bridge chip heat sink. The condition of the South Bridge may be a little less.

These issues can sometimes significantly affect performance, and at some point you will not be able to turn on your computer.

It's too high.

Or encounter some abnormal program interruption.

Either you, the power cord was mentioned.

It clicked off.

It should be a bad heat dissipation,Open the case,Clean up the CPU inside,Dust on the graphics card fan and power supply,If it doesn't work,It's necessary to replace the CPU fan with a little more power,Recently, there are a lot of problems,It's all when the machine was configured before,The fan power is small,In addition to the current online game, it's quite big,The computer has been running for a long time,Useless system garbage,There is more dust,Running large online games, etc.,CPU occupies more,Can't quickly dissipate heat,Resulting in high CPU temperature,Cause computer protective shutdown。

There are many reasons for this, one is hacking, but the chances of this for individual users are not very high. Then the other thing is the hardware.

Many times, when we go to the computer city to buy a computer, unscrupulous computer dealers, in order to make some money, secretly replace the power supply that comes with the chassis we buy with some very cheap computer power supplies, so as to get more profits.

In other words, if your computer's power supply is not very good, when the voltage in your home is unstable, the power supply will jump, and your computer will shut down. Or it will restart. There are many situations when the power supply is unstable, such as when the air conditioner is turned on, or when the TV is more than 25 inches on.

There is another situation, that is, the power of your case power is sticky, because if you press the power button for 10 seconds, it will shut down, but you say that it is a sudden shutdown, it is estimated that this situation is relatively small.

There is a problem with the heat dissipation of the CPU fan, the temperature is too high, and the CPU protects itself.

If the graphics card is too hot, it will cause the computer to restart.

Also, if the voltage is unstable, it will also cause the computer to restart.

It's possible that you used to play with the computer by turning off the power directly, rather than from the computer. This also leads to damage to the motherboard. As soon as the motherboard is broken, every time the computer is running, the motherboard will automatically shut down because it can't withstand such a large amount of heat.

Homeowners are advised to get a new motherboard. Then it's the little fan on the motherboard, so that he can dissipate more heat, and this situation will not occur.

Can I turn it back on immediately after shutting it down?

If not, it should be the automatic protection caused by CPU overheating, unpack and touch the CPU heatsink with your hands to see if it is hot (be careful), check whether the buckle is normal, and reinstall or replace the CPU fan if necessary.

If it can be turned on again immediately after shutting down, the experience feels that the power supply is unstable (40%), operating system conflicts (30%), and memory failures (30%).

1. Software Failure.

1. Virus, use 360 security guard to kill malware and Trojan. 360 anti-virus all-round investigation and killing!

2. There are too many running programs and software conflicts. Turn off unnecessary software. 3. If there is a problem with the system, reinstall the system.

2. Hardware failure.

1. Memory failure, too much dust, and poor contact of memory slots will cause crashes.

2. Poor CPU heat dissipation, resulting in protection and computer crash.

3. Hard disk problem, hard disk has bad sectors.

4. Motherboard problems.

5. The power supply is unstable, which will also cause a crash.

There are many situations in which a software applies.

Second, the hardware and software.

It could be a system crash.

caused by viruses.

Hardware words. It's the power supply that's insufficient.

The temperature is too high. Don't know what your reason is.

Hope it helps.

It could be that the CPU fan is collecting too much dust. Poor heat dissipation. Cause the temperature to be too high and automatically shut down.

Clean up the fan dust. Add some lube.

It's best not to use a computer when lightning strikes, although the current house has a certain lightning protection function, but sometimes it will inevitably break the computer. In general, the most easily damaged are network cards, ADSL, and routers. These network devices, followed by power supplies, motherboards, and so on.

Therefore, when thunder and lightning strike, it is better to use the computer sparingly. When you don't use your computer for a long time, turn off the power supply. Don't be afraid of 10,000, just in case!

It's also good for computers!

1.Let your computer have a dedicated socket, don't plug the computer and the air conditioner, refrigerator, TV or anything together, it is easy to cause voltage instability.

2.Check if the CPU fan is working properly and if the CPU is overheating.

3.Check whether the power supply is working properly, if it is overheated, you just need to replace the power supply.

4.If you don't change the power supply, let the machine rest and rest, open the lid of the case, and use it again. `1

There are many reasons for this. The CPU temperature is too high. The power supply is insufficient. Motherboard issues. But it generally shuts down suddenly, most of the CPU temperature is too high, that is, the heat dissipation is not good.

Hello, you'd better check the CPU cooling system first, see if the dust is big, whether the cooling fan is not rotating badly, under normal circumstances, the possibility of shutdown due to poor heat dissipation is relatively large, the CPU has a limit temperature, if it has reached this temperature and can not be cooled down in time, the CPU will issue a command to force the shutdown, and then there is the problem of power supply or voltage, you first check it simply, eliminate the problem, because the accessories are not easy to find, you can't get it to be repaired, I hope you can adopt, Good luck!

Pretending to be a Jinshan drug bully and a Jinshan guard, I have also encountered poisoning. Or maybe you don't have enough electricity in your home.
