Why can t the computer shut down the win7 system?

Computer shutdown abnormalities can be analyzed from the following aspects: 1. Computer viruses: network viruses were rampant in the past, and now you basically don't need to consider this (solution: reinstall the system).

2. Graphics card driver: Today's computers are prone to appear, due to continuous hardware upgrades, drivers are constantly updated, and the driver is installed incorrectly.

3. Software compatibility: There may also be software installed, which causes conflicts with the hardware graphics card driver or power virtual management driver, resulting in system instability.

4. Being remotely logged in: If someone maliciously controls the computer, it is recommended to disinfect and do a good job of security protection.

5. Restore with restore points.

6. Repair the computer with the tool options of image, system CD, and boot interface.

7. Reinstall the system, if it is an unknown reason, it is usually due to improper operation to change the system settings, and reinstallation can solve most of the problems.

In response to this kind of problem, it is recommended to check the system log, see what is the record of the shutdown time, check whether there is no problem with the driver installation, and then antivirus, if it is a new installation, it may also be a hardware conflict, which can only find the manufacturer to change the configuration.

Alt +F4 Try or force restart it and you're good to go.

It's stuck in **, right.,You hold down the power button and don't let go.,Wait for his lights to go out.。。。

Forcing a shutdown can be solved, so the computer will be angry

Some files are not finished, so let's start anew.

A forced shutdown can be solved.

Here's how to fix it:

1. There are many factors that the computer cannot be turned off, it may be poisoned, it may be a system problem, it may be a hardware problem, or it may be a setting problem, so it is necessary to eliminate it one by one.

2. First, the possibility of poisoning. If the computer may be poisoned and the computer cannot be shut down, you need ** antivirus software, and then carry out the Trojan horse, click on the overall antivirus, and you can't let go of any of them, and then continue to use the computer after the killing, if not, go to the next step.

3. Second, the configuration file is fixed. If the antivirus can't solve it, you have to carry out this step, the configuration file is repaired, and the specific operation may be more troublesome, so let's take a look at it patiently.

1. The first small step, click the "Start" icon at the bottom left of the computer, and then enter "regedit" in the "Search Programs and Files", click "OK" when you see the result, and then the settings box will pop up.

2. Find the hkey-local-machine software Microsoft Windows CurrentVersion Policies in the settings box, click the "system" folder, and then double-click the "shutdownwithoutlogon" item on the right.

3. After double-clicking, a setting box will pop up, in which the base number will be changed to hexadecimal and the value will be changed to "1".

If such a problem arises due to software conflicts, inappropriate drivers, or system problems, can you restore the system in safe mode, 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.

With DC power, do you click start and then turn off? Or just press the power button? If you press the power button directly,Sometimes the power button of the system may be hibernate or sleep,So you need to set it up in the power options in the control panel,Once my win7 (notebook) just can't shut down,Clicking on ancient Egypt or pressing the shutdown button doesn't work,I can only put the power cord,And then there is no such situation,Good luck...

It may be too wet or dusty, take care of it. I was the same with the whole machine before, I deducted the battery at the time, and I didn't have the same problem after maintenance.

Remove the battery and blow it with a hair dryer.

Buckle the battery and take it to the repair point to repair it!

It has to do with it, because after you run out of battery, the computer will shut down cold, resulting in the loss or corruption of files in the system, you can go into the safe mode to repair it when you start it and then start again, if not, you can do it all over again.
