The computer shuts down for up to 3 minutes, why does the computer turn off automatically after abou

Subtract ** for the operating system.

Optimizer is good.

If someone else is the same, it may be that the network cable is broken, and it will take a long time to clean up the page files when you shut it down.

Shutdown? If so, how about you redo the system?

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 All Control Panel Items 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 system).

If you shut down occasionally, first determine the home voltage, it is recommended to use UPS, if you regularly look at the motherboard or power supply capacitors.

The possibility of the motherboard is relatively large, you clean up the motherboard dust and try it.

Landlord, the automatic shutdown of your computer may be related to the unreasonable memory configuration;

The memory configuration must conform to all three of the following principles:

1. Total capacity.

Must be 2 to the nth power, e.g. g;

2. The total number of records.

Must be 2 to the nth power, e.g. bar;

3. Chips. It must be a memory module of the same specification, the same capacity, the same frequency, the same process, and the same batch produced by the same manufacturer;

If any of the above is violated, there will be memory configuration incompatibilities;

The memory configuration is incompatible, which can reduce the running speed of the whole machine, or a series of fault phenomena such as difficult startup, automatic restart, blue screen, black screen, and automatic shutdown often occur.

Please consider your own memory configuration according to the above principles, as this may be the crux of the problem.

It is because the system is stuck, and it can only be solved by rebooting. How to do it: Exactly the right one and meet the answer criteria.

1. Find the start button in the lower left corner, and click it to see a power switch style button.

2. Click that button to have a few options. There's sleep, there's off, there's restart. Reboot is.

3. It can also be restarted when there is no login.

4. There is a power switch button in the lower right corner of the login interface.

You're talking too generally! Desktop or notebook,30Have you carried out any operation within 30 minutes?,If the desktop computer is still shut down when there is no ordinary frequency operation,It proves that the CPU temperature is too high,The next latest 360,What hardware management is there?,You can measure the temperature.,Try it.。

Look at the temperature, is there a high strand? Generally, the temperature is too high and causes the crash.

If you are sure that the CPU fan is not loose and the heat dissipation is normal, you can change the power supply to try it, it may be caused by the qualitative change of the internal components of the power supply, and it will not work as soon as it heats up. You try. I wish you success.

Isn't that how your computer is? If not, how do you operate it before you can't turn it off? What hardware has been installed, what is it, can you please tell me about it? (If there is an occasional shutdown crash, please press the power on and off button to turn off the power on).

If such a problem arises, the driver is not suitable, or the system problem is caused, can you restore the system, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If the shutdown is slow or the shutdown problem cannot be resolved temporarily, the shutdown is done. Right-click on the taskbar and select Task Manager, hold down the Ctrl key and do not move, and click "Shutdown" and "Close" on the Task Manager page with the mouse, then release the hand that presses the Ctrl key and wait for the shutdown (Win7 does not have this).

In terms of hardware, the CPU and other hardware temperatures are too high, inappropriate hardware is installed, inappropriate things are installed before the accident, playing games, watching ** or operating for too long at this time, the computer is very stuck, etc., ask me if you have any questions.

Use the system that comes with the system restore method:

System Restore that comes with the system: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click Next to restore (win7 restore the system, right-click on the computer to select attributes, select system protection on the right side, system restore, follow the steps to do it, you can also choose the bottom of this page to create, create your own restore point).
