In this way, the machine is prone to crash while it is running. You can use special tools and software to troubleshoot, if the damage is serious, you can only replace the hard disk.

In addition, for motherboards that do not support UDMA 66 100, you should pay attention to the setting of the hard disk operation mode in CMOS.

When WinXP is shut down or restarted, it always stops at the "Saving System Settings" place, the hard disk light is no longer flashing, and the system does not respond! What is the reason for this? a：

When starting and shutting down the computer, the system always prompts: "Saving system settings", this is mainly because there are too many files loaded after the system runs, resulting in the system running too many files in a short period of time and cannot be aborted, we can use the "Ctrl+Alt+del" key to bring up the "Windows Task Manager", click "Process" to view the currently running files. To solve this kind of problem, type the "msconfig" command in "Start Running", and click the "Startup" tab item in the "System Configuration Utility" dialog box that pops up.

In addition, too much fragmentation on the hard disk can also cause the system to shut down or reboot for a long time or even cause a crash, so we also need to regularly defragment the hard disk. If you set up a sound file when you shut down or log out, and if this sound file corruption can also cause this kind of problem, we can go to the Control Panel Sound & Audio Settings to remove the sound. If the problem is still not solved, we can right-click on "My Computer", select "Manage", and select the "Service" item in the "Services and Applications" item, and disable unnecessary services in the window on the right.

Automatically close the stop responder when powered off:

At the start of Run type regedit hkey users default control panel in the right window of the desktop, change the value of autoendtasks to 1

Just log out or restart.

The shutdown is often very slow, and if it hasn't been turned off for more than 10 minutes, it should be a crash. You can try to uninstall Lenovo's one-click recovery monitoring to see if it's much better.
