My computer can t shut down, it s broken, it s starting to shut down, press the power button to shut

In most cases, it is a virus Trojan that causes the computer to fail to shut down normally, and the more typical virus is the kidnapping Trojan, which is a new type of highly destructive Trojan, which is different from the traditional virus, it is by kidnapping the system file registry to achieve boot startup, resulting in the computer shutdown button is missing.

The sound file is corrupted and the computer cannot be shut down.

Incorrect settings will cause the computer to fail to shut down properly.

4.The Advanced Power Management (APM) feature on your computer can also cause shutdown, freeze, or black screen issues.

The computer shutdown does not solve the problem:

1. The computer was damaged by a Trojan virus, and the registry information was maliciously changed. The solution is as follows:

Step 1: Enter the main interface and enter [Kill Trojan];

Step 2 After installation, click on "Kill Trojan" to use the full scan function.

2. If the user mistakenly modifies the computer shutdown configuration file, the repair method is as follows:

1. Start "Run", enter "regedit" in the "Run" dialog box, click "OK" to find the following: hkey-local- machine software Microsoft Windows CurrentVersion Policies, click the "system" folder, and then double-click the "shutdownwithoutlogon" item on the right.

2. "Start" "Run", enter "Run" in the "Run" dialog box, and then click the "OK" button. In the Group Policy window, double-click Administrative Templates, Taskbar, and Start Menu, and then double-click the Remove and block access Shutdown command on the right. In the Remove and Block Access 'Shutdown' Imperatives window, click the Settings tab, select Disabled, and then click the OK button.

3. First of all, you can determine whether the "Quit Windows" sound file has been destroyed - open the "Control Panel", open "Sound", and cancel the "Quit Windows" sound. If Windows shuts down normally, the problem is caused by quitting the sound file, and you can fix this by restoring the sound file from a backup or by reinstalling the program that provided the sound file, or by defining "quit Windows" as silent.

4. When the computer starts, you can enter the CMOS setting page, and focus on checking whether the CPU external frequency, power management, virus detection, IRQ interrupt opening and closing, disk boot sequence and other options are set correctly. You can refer to your motherboard's manual for specific settings, which has very detailed settings instructions, if you really don't know about its settings, it is recommended that you directly restore the factory default settings.

5. To check whether the "Advanced Power Management (APM)" function can also cause the shutdown crash or black screen problem, you can open the "Device Manager" and open the "System Devices". In Advanced Power Management, remove the Enable Power Management selection. If the computer shuts down gracefully, the cause of the problem may be APM. "

It should be the wrong connection, press the restart button to try ......

The correct way to use the computer's shutdown button to force a shutdown is to press and hold the shutdown button, when there is a phenomenon that the shutdown button cannot be shut down, it is usually the shutdown button itself is damaged or the key is loosely connected to the motherboard.

The effect should be the same for both.

To turn off the computer button, you need to press and hold for a while, and then let go.

See if there's no real shutdown.

The reasons and solutions for not shutting down the computer are as follows:

1. First of all, there is some software interference. Some software can't be shut down without closing it, and these software just click the "close" button and don't close, just minimize to the taskbar:

2. For this kind of software, it is best to pay special attention to it, it is best to right-click the software icon in the lower right corner of the taskbar and select the "Exit" or "Close" command:

3. When this software is exited, it can be shut down according to the normal method.

4. Sometimes, the desktop is still displayed after the normal "shutdown" command, and the computer cannot be shut down normally, so check whether there is any process interference, especially if there is a program that can not close the process normally and stop responding, check its process and force it to end. This type of process generally has a high "memory usage".

5. Next, check whether there is a "rundll32" process, there are generally a large number of rundll32 processes that cannot be shut down normally, and you can force it to end

6. If the general shutdown operation is still invalid, you can try to use the command to shut down the operation. Enter "shutdown -s -t 30" at the DOS prompt or in the "Run" dialog box

7. Use this command to pop up a 30-second shutdown countdown shutdown dialog box

8. During this time, the shutdown can be canceled by the "shutdown -a" command

9. In addition, many times it is not really impossible to shut down, it may be that the system is junk files or has run too many programs that cause slow shutdown, it is recommended to log out first and then log in, and then shut down to try. But if that's the case, it's better to optimize your computer first

10. If there is third-party software such as 360 installed, you can also use these software to achieve shutdown operation

11. If you can't shut down after trying multiple methods, it is likely that the system files are corrupted, and it is recommended to repair them first. At this point, you need to press the power button on the host to force the shutdown.

The computer can't be turned off, it's generally a software problem, take a look at what software has been installed recently, uninstall it, and try again.

Use the windows cleanup assistant to clean up the trojan, the antivirus software to kill the virus, clean up the garbage, and you can basically shut down. In special cases, pressing the power button to turn off is nothing.

Pressing the shutdown button to restart is the same as cutting off the power directly.

Directly press the power to shut down the computer The biggest impact on the computer is the hard disk, the most obvious manifestation is that when the computer is restarted, it takes a period of self-test before it can enter the system.

Forced shutdown is the most harmful to the hard disk, because the hard disk is a mechanical structure, the head is rotating rapidly when working, when the normal shutdown, the system will give the hard disk to stop working, and then the head will return to the position when it stopped working, waiting for the system to shut down, if the forced shutdown, the head suddenly loses power during rotation, and the loss of power is likely to scratch the platter, resulting in physical damage to the hard disk. In addition, forced shutdown can easily cause the system to lose files.

Press the power button to shut down the hard drive, you try to reinstall the system.
