1. The operating system and motherboard do not support ACPI or APM well enough.
2. Various hardware other than the motherboard does not support ACPI or APM well enough.
3. Hardware driver bugs.
4. Motherboard BIOS needs to be improved.
5. System support for fast shutdown is not good enough (only for windows98).
6
Some memory-resident programs exit before shutdown and conflict with the system shutdown process.
7
Virus.
8
Failure of the disk subsystem, such as a lack of compatibility of the IDE driver with the system.
Of course there are many other aspects of the reasons, the author can not possibly repeat them here. Because my friend is a new installation of the operating system, in addition to the driver of the sound card (other hardware due to the operating system comes with the driver), has not yet installed a variety of applications. So I will focus on the problem on the motherboard and operating system support for power management is not perfect. Adhering to the principle of first easy and then difficult, the first into the motherboard's CMOS settings interface, in the power

APM off, boot into the system, and then shut down, the computer is still restarting.
Reboot windowsXP, go to the control panel power management, click on the "hibernation" menu, at this time to enable hibernation in the unchecked state, so check the "Enable hibernation", but still failed to work.
Re-enter the power options in the control panel, click on the "Advanced Power Management" sub-page, the system displays: This machine supports Advanced Power Management (APM), the use of APM can reduce the system's power consumption. At this time, "Enable Advanced Power Management Support" is selected. I don't hesitate to remove "Enable Advanced Power Management Support", it's okay to consume more power, but I can't shut down the computer normally, it's weird. The next step is of course to shut down the computer, OK, "now you can safely shut down" a few words out, haha, quite kind of it.
This case is due to the system's support for advanced power management is not good enough to cause, or can be upgraded through the BIOS to eliminate the problem, just this motherboard is a long time ago, may not have been able to find the updated BIOS, so I have not tried to ATX motherboard, it is recommended that you still enable the advanced power management, otherwise there may be trouble in this article from the Ichimoku information net:
