For Windows XP, because it uses the NT core with high security performance, the system runs fairly stable. In addition to the slow shutdown speed, shutdown failures rarely occur under normal circumstances. However, you should also pay attention to some of the following symptoms. 1. Shutdown and restart failure This fault is the most common fault in the Windows XP operating system shutdown failure. The cause of the failure may be due to the following reasons: 1) The system setting is in the default situation of Windows XP. When the system is in error, it will be automatically restarted. When the user shuts down, if the system fails during the shutdown process, it will be restarted. Start your computer. Turning this feature off often resolves the failure of an automatic restart.

If you are using "Enable Advanced Power Support" when the failure occurs, try to cancel it. If the failure occurs, you are using the cancel "advanced power support" and try to enable it. Will be solved. 3) USB devices are not worrying Now when USB devices are popular, what U disk, mouse, keyboard, modem, etc., have everything.

An external USB Hub connects the USB device to the USB Hub instead of directly to the USB port on the motherboard. 2, shut down the blue screen 1) Windows XP has a bug Windows XP has a shutdown bug, if your computer often shuts down the blue screen during the shutdown process, and the fault is intermittent, press & ldquo; Ctrl + Alt + Delete & rdquo; The key is also unresponsive, so you can be sure that your system has not been patched. Please download the SP1 patch package and patch it. Generally it will be fine. 2) There is a problem with the driver of the innovative sound card. If you are using an innovative sound card and a blue screen appears during the shutdown process, the error code is “0X0A”, then enter the device manager, delete the sound card, refresh it, and manually install the latest one. Driver with digital signature. 3) Logitech mouse and keyboard are not perfect If you are using Logitech's network keyboard and installed Key Commander software to drive the corresponding network function of the keyboard, it may cause the shutdown to become a restart failure. If the driver for your Logitech mouse is MouseWare 8.6, it will cause a blue screen shutdown, you can only solve the problem by uninstalling the driver. 3, shutdown can not automatically cut off the power As we all know, shutdown is closely related to power management, the cause of shutdown failure is likely to be poor power supply management system support.

It may be a mistake to modify the BIOS related power management options. If you are familiar with the BIOS settings, please enter the BIOS and try to modify the BIOS related options for power management. If you are not familiar with the BIOS, then simply select the "Load default setup" option to restore the BIOS to the factory default settings. 3) Office XP also gets into trouble Ctfmon.exe in Office XP has always been a controversial issue. Ctfmon.exe is Microsoft's text service file.

Note: This article describes some of the shutdown failure cases that I have encountered, which you can refer to at your discretion. 4, improper power supply settings can not be properly shut down after installing WinXP can not automatically shut down, if the above various reasons are excluded, it may be that the power option settings in its control panel is not correct, please check your settings to ensure that ACPI and APM can normal work. There is also a motherboard system BIOS APM (Advanced Power Management) and Win XP are not fully compatible (more than AMI BIOS), so it can not automatically shut down. Selecting the shutdown turns it into a restart of the system. In this case, it can only be manually turned off (press the power switch for 4 seconds and then release it, if it is less than 4 seconds, it will be invalid). The fundamental solution to the problem is to upgrade the motherboard's system BIOS to the new version.
