I believe that the use of Windows XP friends will encounter XP can not shut down the situation, although not unable to boot so depressed, but also very uncomfortable things!
1. Corrupted sound files when exiting Windows
First you can determine whether the exit Windows sound file is corrupted-open Control Panel, turn on sound, and cancel the "Exit Windows" sound. If Windows shuts down correctly, the problem is caused by exiting the sound file, to resolve this problem, you can restore the sound file from the backup or reinstall the program that provided the sound file, or you can define "exit Windows" as silent.
2. Too many loading programs
Can run "Msconfig", turn off the startup program.
3, pay attention to "advanced power Management"
Also, the Advanced Power Management (APM) feature on your computer can cause shutdown crashes or black screen problems. To determine if APM will cause a shutdown problem, open Device Manager and open system devices. In Advanced power Management, remove the Enable power management option. If the computer shuts down normally, the problem may be APM.
4, startup is shutdown failure
You often encounter when Windows just started the show "You can safely shut down the computer," or at the beginning of the shutdown or shutdown when the failure to reboot. This type of failure is generally caused by damage to Wininit.exe or Vmm32.vxd files. The workaround is to reset the two files from the Windows Installer Compression pack. In the Windows\\System subdirectory, rename Vmm32.vxd to vmm32.xxx for backup, then open System Tools, select System Information--"System File Checker" in Tools, select "Extract a file from installation disk", and enter " Wininit.exe "or" Vmm32.vxd ". Repeat this step to replace the file Wininit.exe or Vmm32.vxd.
5, Config.sys or Autoexec.bat have problems
Extract a file from the installation disk
In addition, you can check for conflicts in Config.sys files or Autoexec.bat files. Use a text editor to view the contents of these two files to see if there are any extra commands, or "REM" to prevent certain statements from being executed, and then to exclude them until a conflicting command is found.

6, check the CMOS settings
CMOS settings will also cause computer shutdown problem, everyone in the computer startup can enter the CMOS settings page, focus on checking CPU FSB, power management, virus detection, IRQ in the disconnect, the disk boot sequence, and other options are set correctly. Specific settings you can refer to your motherboard manual, which has a very detailed set of instructions, if you are not very understanding of its settings, we suggest that you directly with the factory default settings can be.
