Newly assembled computers sometimes shut down automatically

Isn't it because the power management options in the desktop properties are set up for power management?

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

Suddenly, there was a short power.

There are several reasons for shortness:

Overheating, protective shutdown. (Check to see if the CPU fan is rotating normally, or if it is already spinning very slowly).

2.The power supply of the host is insufficient.

3.Unstable voltage is also a common cause of sudden shutdown.

CPU overheating, this situation occurs, I can't say, it's hot in summer, pay attention to heat the case, and your power supply is a little low.

Silicone is evenly applied to the CPU, don't apply too thickly. You can see your ** by scraping it with a wooden stick, your CPU silicone is coated a little too much, and too much is not conducive to heat dissipation.

In addition, you have to make sure that the CPU is in full contact with the center of the cooling fan, as if you are not, and in addition, your fan looks very average, and it seems a bit expensive to 45.

Let the after-sales take a look, just bought, don't toss it yourself, there is a warranty.

It can't be that the CPU fan is not plugged in, right?

There are four reasons why your computer shuts down automatically:

1. There is a problem with the power supply, when the filter capacitor of the power supply is bulging, it is normal when it starts to boot, it has been used for a period of time, due to the bulging, resulting in leakage, insufficient power supply, the power supply starts to protect itself, cut off the power supply, and shut it down, treatment method: replace the power supply;

2. The CPU fan is broken (or there is too much dust, and the fan is stuck) or the card is taken off, when the fan is broken, the CPU cannot be cooled, and when this temperature reaches the set temperature, the motherboard starts self-protection and shuts down. The clip of the radiator will also increase the temperature for the same reason, the treatment method: clean the dust or replace the CPU fan or reinstall the clip cavity;

3. There is a virus in the computer, which causes the system CPU occupancy to be too high, and the memory resources are exhausted, which also causes a crash, and then it shuts down. Solution: Antivirus in safe mode, or reinstall the system, (one-click restore);

4. The voltage is abnormal, that is, the voltage is normal when it is turned on, after playing for a while, the voltage does not reach the specified voltage of starting the computer, the power supply starts low-voltage protection, the power is turned off, and the power is shut down.

Reason for automatic shutdown of the computer:

1.viral causes;

2."Automatic shutdown and restart when the computer encounters a serious error" is enabled;

3.Severe memory errors causing the system to crash (software issues);

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.

Solution: If the above sudden shutdown phenomenon keeps happening, check whether the heat dissipation of the CPU is normal. Turn on the case to see if the fan blades are working properly, and then enter the BIOS option to see the speed of the fan and the working temperature of the CPU.

If you find that it is a fan problem, you will carry out relevant dust removal maintenance on the fan or replace it with a better quality fan. If you rule out the hardware cause, enter the system, overwrite the installation power management from the installation CD of "Windows", and then thoroughly check and kill viruses. When these factors are eliminated, the cause of the failure may be the aging or damage of the power supply, which can be confirmed by replacing the power supply method, and replace it with a new one if the power supply is broken, and it must not be used continuously, and the hardware will be burned.

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 that causes the computer to shut down automatically, and it is unlikely that this problem exists.

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

Ask a question about how a newly assembled computer always shuts down automatically.

If the computer is unstable, the system file of the computer is corrupted, and the system needs to be reinstalled

2. Shut down and restart the computer that needs to install the system, and click the F12 button when restarting to enter the BIOS system interface;

3. Use the arrow keys to control the cursor movement in the BIOS interface, use the Enter key to control the selection, and find the USB flash drive boot option;

4. Click the USB flash drive to start and enter the USB flash drive installation system, and select the Ghost installation option in the installation system interface;

On another computer, ** needs the installed system image file, and place it in the installed USB flash drive; Shut down and restart the computer that needs to install the system, and click the F12 key when restarting to enter the BIOS system interface;

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

1) If it automatically shuts down or standby without operating, 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, click Hardware & Sound on the left, then Power Options on the right Change schedule settings Select Turn off the monitor (select Never or Set time), select Change computer sleep time, and select Never or select the appropriate time (Win7 or Win8) from the drop-down list next to Make computer sleep.

See if it's caused by the settings above.

If you have any questions, please ask me.

Is your voltage not very stable?

You pay attention to the uproar, there may be high-power electrical appliances that will automatically shut down or restart when used, if it is this tired problem, it is recommended to match a voltage regulator, but it doesn't seem to be a good match, I want to match it.

For a while, I didn't know where to sell.

Otherwise, it's upstairs.

Supplement. If yes.

If it goes black or restarts in a flash, it is mostly a voltage problem, and it is recommended to try a different power supply.

There are four reasons why your computer shuts down automatically:

1. There is a problem with the power supply, when the filter of the power supply is bulging, it is normal when it starts to boot, it is used for a period of time, due to the bulging, the mega key becomes leakage, the power supply is insufficient, the power supply starts to protect itself, cut off the power supply, and it is shut down, and the treatment method: replace the power supply;

2. The CPU fan is broken (or there is too much dust, and the fan is stuck) or the card is taken off, when the wind is broken, the CPU can not be cooled, and when this temperature reaches the set temperature, the motherboard starts self-protection, and it shuts down. Falling off the heatsink clip will also increase the temperature for the same reason, as above, and the treatment method is to clean the dust or replace the CPU fan.

Or reinstall the clip into the cavity;

3. There is a virus in the computer, which causes the system CPU occupancy to be too high, and the memory resources are exhausted, which also causes a crash, and then it shuts down. Solution: Antivirus in safe mode, or reinstall the system, (one-click restore);

4. The voltage is abnormal, that is, the voltage is normal when it is turned on, after playing for a while, the voltage does not reach the specified voltage of starting the computer, the power supply starts low-voltage protection, the power is turned off, and the power is shut down.

There are three ways you can start:

1. Open the case to see if the CPU temperature is high, and see if the memory is plugged in tightly.

2. Change the power supply and give it a try, the colorful power supply is okay. It doesn't have to be a profiteer.

3. There is also a complete anti-virus of the hard disk, which is also one of the reasons for the shutdown.

In my experience, you have not bought this celery for a long time, if it is a hardware problem, you can negotiate with the merchant. The merchant is treacherous, and Suichun will be responsible for you, and no one will lose credibility because of a customer.
