The computer always shuts down automatically for some reason, asking for help

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, add new heat dissipation silicone grease, if the heat dissipation fan is broken, change it. If it's not a problem, it may be caused by problems with motherboard parts or power supplies, voltage instability, hard disk failure, hardware overclocking, etc., and the new hardware is incompatible. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a scenario that suits you from the drop-down list in Power Usage Scenarios, and set Never in the list of Monitor Off, Hard Disk Off, System Standby, and so on below (or set a suitable time).

Open the control panel All Control Panel Items Power Options Select Turn off the monitor (select Never or Set Time) Select Change the computer sleep time on the left, and select Never or select the appropriate time (Win7 system) from the drop-down list next to Make the computer sleep.

See if it's caused by the settings below.

It depends on whether you are a laptop or a desktop.

If it's a desktop.

Teach you one of the most convenient and simple ==

Go to a store that sells toys yourself.

For 5 bucks, buy a balloon blowing bag.

Then go home and unplug it, remove all the wires, and take it out.

Open the case side cover.

Blow it yourself. Blown exceptionally clean.

If you finish blowing dust and the chassis is particularly noisy, I'll teach you a way.

The premise is that you are a desktop computer, not a laptop, and you are more willing to do it yourself.

Connect the power cord first, don't connect the other cables.

Then turn it on, after the fan turns up, first press and hold one with your hand, a little lighter, this one in your hand doesn't turn.

Listen to the noise level, if it is small, it proves that there is a problem with you holding this down.

The voice still hasn't changed. Just change it and exclude it one by one.

Don't move the fan of the power supply. You can't get it.

If you really don't want to do it, then you have to work hard.

Grab your console and head to your local electronics market.

Just find someone to handle it for you.

30 bucks are all done!

If you have any questions, please follow-up, thank you! ~

2 reasons: 1. The temperature is too high. Clean the radiator and replace the fan.

2. The power of the power supply is insufficient. Replace the power supply.

If the temperature of the CPU is too high, clean the dust on the heat sink and re-apply the thermal grease.

There is a problem with the fan heat dissipation, check!

1. Open the case and check the fans of the power supply, PCU, graphics card, etc., to see if the speed is normal? Then touch the heat sink with your hand to see if it is hot.

2. Wash all the dust in the chassis and clean it with 95% alcohol and a brush.

3. Clean all the boards and plug them back in.

4. If it is still automatically shut down, please check the system, if it can't be checked, reinstall it, which is the simplest and most direct.

The reason for the CPU temperature to be too high is the most, and you can add thermal grease to the heat sink regularly, which can generally be solved.

Get a test software and try to see if the CPU temperature is too high.

The computer often shuts down automatically inexplicably, first see if it is a software problem, you can first enter the safe mode of the system to restore it!!

There's a lot of dust. Clean the fan and heatsink of the CPU graphics card motherboard chip.

It should be a bad heat dissipation,Open the case,Clean up the CPU,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 like this,It's all when the machine was configured before,The fan power is small,In addition to the current online game is 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.!

The computer shuts down automatically, why? How to solve it?

1. The CPU temperature is too high, and the self-protection causes automatic shutdown.

Solution: Check whether the fan is running normally, whether the heatsink is tightly integrated with the CPU, and if possible, replace the heatsink and fan with reliable quality.

2. The power quality is not good.

Countermeasures: the power quality is not good, resulting in poor voltage, filtering, and current function, and the system is sometimes automatically shut down due to low power supply quality.

3. The quality of the motherboard is not good.

Solution: All devices are plugged into the motherboard, if the quality of the motherboard is not good, it is likely to cause inexplicable symptoms in the system, so it is very important to choose a motherboard with reliable quality. The saying that you get what you pay for is also very reasonable.

4. Affected by viruses.

Countermeasures: Some viruses will start the system countdown and shut down on their own initiative, patch the system in time, and it is very necessary to check and kill the system regularly.

Your problems are generally caused by the above aspects, the problems caused by the software, the heat dissipation problem is very easy to solve, and it is difficult to deal with the quality of the hardware itself, and the best way is to replace the hardware. Most of the time it could be a hardware issue, the chassis is too hot.

Medium virus.

It should be a software issue.

If the hardware overheats, it should crash directly.

Either the plug is likely to loosen the rats.

The answer to the question is often the most unexpected.

Smack? See if the power cord isn't plugged in tightly.
