Why the computer can’t be turned off

Why can’t the computer shut down or shut down normally?

Viruses and Trojans are usually the main reason why computers cannot shut down properly. One of the typical viruses is the kidnapping Trojan, which is extremely destructive. Different from traditional viruses, kidnapping Trojans start by modifying the system file registry. The main performance of this Trojan is twofold: 1. Forcibly modifying the browser homepage; 2. Unable to delete desktop icons, etc.

2. Computer shutdown related configurations were accidentally modified by the user

What to do if the computer cannot be shut down

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

After downloading and installing Kingsoft Defender, click "Check and Kill Trojans" to use the full scan function

2. Start"→"Run", enter "regedit" in the "Run" dialog box, click "OK" to find the following: HKEY-LOCAL-MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policiesClick "system ” folder, and then double-click the “shutdownwithoutlogon” item on the right.

3. Open the "Start" menu, click "Run", enter "gpedit.msc" in the pop-up dialog box, and then click "OK". In the opened "Group Policy Editor" window, double-click "User Configuration" → "Administrative Templates" → "Start Menu and Taskbar", and then double-click "Block access to shutdown, restart, log off commands" on the right. In the "Prevent access to shutdown, restart, logoff command properties" window, switch to the "Settings" tab, select "Disabled", and finally click "OK".

Why can’t my computer shut down

Windows cannot shut down

There are many reasons for this failure, the solution is:

1) Caused by computer hardware.

The motherboard BIOS does not support ACPI very well. It is recommended to upgrade the motherboard BIOS, which usually solves the problem.

The computer's power supply quality is poor, resulting in the inability to shut down properly. It is recommended to change to a good quality power supply.

2) Caused by computer software.

Check the Bootlog.txt file. The records listed below may cause the computer to fail to shut down. You can find out the reason based on the situation displayed in Bootlog.txt in the root directory of the boot disk in your computer:

Terminate=Query Drivers There is a problem with the driver

Terminate=Unload Network Unable to load network driver conflict

Terminate=Reset Display There is a problem with the graphics card settings or graphics card driver

Terminate=RIT sound card or some old mouse driver and timer related issues

Terminate=WIN32 Some 32-bit applications lock the system thread

3) Check [Advanced Power Management (APM)]: Open [Start] | [Settings] | [Control Panel] | [System], and then click [Device Manager]. Expand [System Devices] | [Advanced Power Management], click the [Settings] option, and remove the check mark in front of [Force APM]. If the computer can shut down normally after restarting, the cause of the problem may be APM, and the advanced power management function should be turned off.

4) Disable quick shutdown: Click [Start] | [Run] menu, enter "msconfig" in the command box and click [OK]. The [System Configuration Utility] window will appear. Click the [General] page, then click the [Advanced] option. In the [Advanced Troubleshooting Settings] window that appears, select the check box in front of [Disable Quick Shutdown]. If the computer shuts down normally, there is something wrong with the quick shutdown item.

5) Check whether all applications have been closed when shutting down. If not, you can close all applications. Because some application software may not be closed properly, and the system cannot end the application normally, resulting in a malfunction.

6) When you use IE 5 or higher to surf the Internet, please note that they still occupy a large amount of system resources after exiting, usually making the system's available resources less than 80%. After that, it is easy to make errors when running other software. , it is likely that the system cannot be soft shut down.

7) When some software is finished, the system may not shut down normally because some operations performed have an impact on system data or files. This situation is different from poor software design, which may be due to the system itself being unfavorable to its own protection, and sometimes related to multitasking. Although Windows XP has the feature of multitasking, some large software can easily cause malfunctions when multitasking is executed simultaneously, such as illegal operations, blue screen failures, and crashes. The problem of being unable to shut down caused by this situation usually does not occur the next time you turn on the computer.

8) BUGs in some programs or some 16-bit software may also damage system data or files in memory. Memory-resident software can also easily cause conflicts, resulting in abnormal system shutdown. It is not easy to find software with such problems. Select "Start" * "Programs" * "Accessories" * "System Tools" * "System Information" to open the "Microsoft System Information" dialog box and select "Tools" * System Configuration Utility" can be set to allow or disable multiple Windows XP-resident programs in "Startup". Other problematic application software can only find their shortcomings during long-term use in order to avoid errors in time.
