Why does my computer shut down automatically for half an hour?

1. It may be caused by poor heat dissipation, open the case to see if the CPU fan, graphics card fan, and computer fan speed are normal, and whether there is too much dust.

2. The sleep function is not equal to the scheduled shutdown, the sleep is to save the state of the computer in the hard disk at that time, and then shut down, at this time the computer is in a low-power state, when you press the boot button again, the system will return to the running state of the last hibernation.

3. Cancel hibernation, and then right-click on the desktop -- Properties -- Screen saver -- Power -- turn off the hard disk and set the system standby to "Never".

The most important thing is to check whether your case is well heated.

Looking at this look, it is estimated that there is a problem with the heat dissipation system.

The longer the computer is used, the heat dissipation capacity decreases.

Clean the fans of your CPU and graphics card properly.

The heat dissipation is not good, your machine (CPU, motherboard, whatever) temperature is too high It will automatically shut down, it is the machine self-protection, you ** software to see the temperature, if it is too high, go to the computer store and press a fan, I just pressed a 10 yuan, but we know each other, hehe...

As the machine ages, the fan and power supply should be replaced.

Then clean up your computer's main chassis.

I guess I should have thrown away the learning machine from 4 years ago.

Tools to clean up the chassis.

Brushes that are larger than paintbrushes cannot be used.

and a powerful hair dryer.

Heat dissipation issues It is recommended to disassemble the chassis and clean it

It is also possible that the parts are aging

The student level is configured

If the heat dissipation is not good, it will crash no matter how high the temperature is.

Check the fan in the main unit.

There is no problem with you changing the power supply, but the capacitor in your power supply is not able to charge and discharge, and the capacity is not enough. ,, dude is a power issue.

Isn't it hot to touch the graphics card and drink the CPU heatsink.

These two reasons may be more likely to cause it.

Change the fan, change the power supply.

It's time for a new one.

Reason for automatic shutdown of the computer:

1.The host has poor heat dissipationThis is the most common one, which is mainly manifested as: abnormal computer sound, such as the sound of a fan turning; There are burn marks on the motherboard and other accessories, or there are burnt smells on the smell.

Smell; The temperature of major components such as the CPU, such as the temperature of the CPU, is too high.

2.Destruction of virus TrojansIf there is a virus Trojan intrusion, then the core components of the system will be damaged, and the computer is likely to shut down automatically.

3.The impact of running the software,Many software will have the operation of automatically shutting down after completing the task in the settings, the common ones are Thunderbolt, Express, anti-virus software, etc., mainly because this kind of software is relatively time-consuming, so it will automatically shut down the computer after completing the task.

4. Procedural issues, some programs will often occur automatic shutdown phenomenon in use.

5. BIOS settings, go to the BIOS to restore the default settings, and then rule out the automatic reboot or shutdown of the BIOS cooling preset.

6. Power failureThis situation often occurs in the case of excessive system load, the load is too large, the operation of the hard disk and CPU is aggravated, and the power supply can not withstand the sudden increase in voltage, and the computer will shut down by itself, and a larger power supply is needed.

7. The chassis is too dustyIf the computer is used for a long time, it will cause too much dust in the chassis, which will cause the motherboard to short circuit or poor heat dissipation, which will cause the computer to shut down automatically.

8. The indoor temperature is high, high indoor temperatures, especially in summer, and long running of large programs, such as 3D large online games, etc.

The solution to the automatic shutdown of the computer:

1. Install Master Lu and other softwareto monitor the situation of your computer at all times; Pay more attention to accessories such as computer exhaust fans.

If found to haveVirus Trojan intrusion, to be used in a timely mannerAnti-virus softwareAntivirus, put in antivirus software, I believe you have already made a choice, I will not mention another here.

Pay attention to their settings when running antivirus, express trains, etc., as many of them are set by default and will be done when they are doneAutomatic power off

For shutdowns that occur when they encounter a running programYou need to uninstall the program software firstForBIOS settingsProblem, just go into the BIOS and restore the default settings.

Indirectly,Power failureIt is also caused by the operation of the system, and in this case, it is necessary to replace the high-power power supply to ensure its demand.

7. DustIt can cause parts aging, pin oxidation, poor contact, short circuits and other failures, so it is necessary to clean the computer regularly.

When using a computer, pay attention to the environment; At the same time, don'tPowered on for too long or running all the timeLarge-scale software.

Reasons and solutions for automatic shutdown of the computer when playing games:

Virus or malware: Use antivirus software to perform a full scan and antivirus to ensure that your computer is not infected by viruses or malware.

Hardware issues: Check your computer's hardware, especially memory, graphics card, CPU, and power supply. Make sure they are all working properly and that there are no signs of overheating or damage. If a problem is found, the hardware may need to be replaced.

Power issues: If your computer's power supply is insufficient, it can cause it to restart automatically. In this case, a higher power supply needs to be replaced.

Game settings issues: Some games may be set too high for your computer to handle and automatically restart. You can lower the game's settings appropriately so that your PC can handle it.

Temperature issues: Your PC may overheat when running games for long periods of time, causing them to restart automatically. You can check that your computer's cooling system is working properly, or consider purchasing a cooler to help dissipate heat.

System problem: If none of the above methods can solve the problem, there may be a problem with the system. You can consider reinstalling your system or using a recovery tool to repair your system.

Is it half an hour each time? Check whether the temperature of the computer is normal, and check whether there are automatic shutdown tasks in the scheduled tasks.

See if your computer doesn't have good heat dissipation and clean up the fan!

Are CPU fans, power supply fans working fine?

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, and add new heat dissipation silicone grease. If it is not a problem, it may be caused by problems with motherboard parts or power supply, voltage instability, hard disk failure, etc., and the new hardware is not compatible. 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 Turn on hardware and sound Power Options Select Turn off the monitor (select Never or Set Time) Select Never or select the appropriate time from the drop-down list next to Make the computer go to sleep (Win7).

Is that a laptop or a desktop?
