First, set the BIOS correctly.

If your computer is connected to a network or USB device, incorrect BIOS settings may cause an abnormal shutdown. Generally speaking, old motherboards are prone to this kind of failure, so you can disable the network wake-up, modem wake-up and USB wake-up options in the BIOS. If you have a usb device, you'd better unplug it.

Second, setting power management shutdown is closely related to power management, and sometimes incorrect power management options can also lead to shutdown failure.

Click "Start → Settings → Control Panel → Power Options", and in the pop-up window, enable or cancel "Advanced Power Support" as needed (if "Advanced Power Support" is enabled in case of failure, try to cancel it, otherwise enable it).

If "Turn off the power when pressing the computer power button (E)" in the "Advanced" menu is not selected, just select it. Third, set the system error function.

In the default settings of Windows2000\XP, the system will automatically restart when an error occurs. Turning off this function can solve the problem of automatic restart failure. The solution process is as follows:

Right-click my computer, select Properties, click the Advanced tab in the system properties window that pops up, and click the Settings button in the startup and recovery column to pop up the startup and recovery window. Just remove the automatic restart option in the system failure column.

Fourth, the waiting time for restoring the system shutdown procedure.

If this time is too short (such as using system optimization) and the shutdown time is too long, the system will think that the program is unresponsive and restart automatically, giving people an intuitive feeling of "shutdown and restart". So you can restore the default time or turn off the automatic restart function.

5. If there is an abnormality after replacing antivirus software or changing network settings, you should pay attention to find out the reason for the change. Pay attention to whether the motherboard supports "advanced power management" well and whether it has been changed. If there is a problem after the change, please cancel the check. If you haven't changed it, you don't need to consider this reason. Generally, the problem can be solved without reinstalling the system. Of course, it's easy to recover if you have gho.

Six, in order to ensure the realization of automatic shutdown, in the BIOS settings, we must put "ACPI".

Function is set to Enabled; APM (Advanced Power Management) function must also be enabled. Check the device manager and find

Computer, right-click and select "Change Driver". Most computers are equipped with advanced power supply.

Intel (ACPI) (Advanced Power Management), if your new motherboard is displayed as acpiuniprocessor pc, you may not be able to soft-shut down! You can choose to change to

Advanced Configuration Power Interface (acpi) or standard.

Windows cannot use the advanced power management of some PC motherboards.

XP support. Generally, computers that use the motherboard of AWARD's BIOS will not have this problem. So far, motherboards that encounter AMI BIOS have this problem, such as Gigabit motherboards. The solution is to upgrade the BIOS of your motherboard, that is, refresh the BIOS, which is a dangerous operation. You'd better ask someone with experience to help you.

The following is the solution of windows xp shutdown and restart. The fault lies in Windows.

The most common failure of XP operating system shutdown. This failure may have the following reasons: 1. System settings clutter the window.

By default, XP will automatically restart when there is an error in the system, so that when the user shuts down, if there is an error in the system during the shutdown, the computer will restart. Turning off this function can often solve the problem of automatic restart failure.

Right-click "My Computer" on the desktop, select "Properties" in the pop-up right-click menu to open the system properties window, click the "Advanced" tab, and click the "Settings" button in the "Startup and Recovery" column to open the "Startup and Recovery" window, as shown in figure 1. Uncheck the "Auto-restart" option in the "System Failure" column, and click "OK".

2. Advanced power management is playing tricks. As we all know, shutdown is closely related to power management, and the failure of shutdown is probably caused by the poor support of power management to the system.

Click Start → Settings → Control Panel → Performance and Maintenance → Power Options. In the pop-up window, you can enable or disable advanced power support as needed. If you use Advanced Power Support in case of failure, please try to cancel it. If you use Advanced Power Support when a fault occurs and try to enable it, the fault will often be solved.

Tried 1, and solved the problem on the 2nd. 3. Don't worry about 3.USB devices.

Now is the time when USB devices are all the rage. You can find everything from USB flash drives, mice, keyboards to modems. I don't know that these USB devices are often the chief culprit of shutdown failure. When the shutdown becomes a restart failure, if there is a USB device connected to your computer, please unplug it first and then try again. If you think it is a USB device failure, it is best to replace the device or connect an external USB.

Hub, which connects USB devices to the USB Hub instead of directly connecting to the USB interface of the motherboard. . ■ Turn it off and give you a big blue face. 1.Windows XP has a Bug.

Windows operating system

XP has a Bug that failed to shut down. If your computer often has a blue screen when it is turned off, and the failure is intermittent, pressing the "Ctrl+Alt+Delete" key does not respond, then you can be sure that your system is not patched. Please download the SP 1 patch package and patch it. Usually. Now you use SP2 more. If yours is not, then change the system. )

2. There is something wrong with the driver of the innovative sound card.

If you use an innovative sound card and a blue screen appears during the shutdown, the error code is "0X0A", then please enter the device manager, delete the sound card, refresh and manually install the latest driver with digital signature.

3. Logitech mouse and keyboard are not perfect. If you use Logitech's network keyboard and install it.

The Commander software that drives the corresponding network function of the keyboard may cause the shutdown to become a restart failure. If the driver of your Logitech mouse is MouseWare8.6, it will cause blue screen failure, and the problem can only be solved by uninstalling the driver.

■ Turn off the power but can't cut off the power automatically.

During the shutdown process, everything is normal, but it stops at "it is safe to shut down" but can't automatically cut off the power supply. You need to manually press the "Power" button on the main chassis panel to turn it off. The reasons for this failure generally include the following aspects:

1. If power support is not turned on, click "Start → Settings → Control Panel → Power Options → High Energy Power Management" in turn, and check "Enable Advanced Power Management Support". 2.BIOS settings are wrong

It may be that the power management option in the BIOS has been incorrectly modified. If you are familiar with BIOS settings, please enter the BIOS and try to modify the power management options in the BIOS. If you are not familiar with BIOS, just select "Load".

Default Settings option, just restore the BIOS to the factory default settings. 3.Office XP has also brought trouble to Office.

Ctfmon.exe has always been a controversial issue in XP. Ctfmon.exe is Microsoft's text service file, as long as users install Office.

XP also installed the "Optional User Input Method" component, which will be automatically called by this file to provide text input support for user input technologies such as speech recognition, handwriting recognition and keyboard. Even if we don't start it.

Office XP, Ctfmon.exe is still running in the background. That's it, which often leads to shutdown failure. You might as well uninstall it.

Click Start → Settings → Control Panel → Add/Remove Programs, and select Microsoft Office XP Professional in the currently installed programs.
