If the Shenzhou notebook cannot enter the system when it is turned on, it may be caused by a virus infection in the system, loss or damage of system files, or hardware failure. Hardware and virus infection can be solved by killing viruses, replacing hardware or repairing them respectively. Software problems are due to Frequent abnormal shutdowns and frequent hot starts account for most of the problems.

The basic steps to shut down Windows are to complete all disk write operations - clear the disk cache - execute the close window program to close all Currently running programs - Convert all protected mode drivers to real mode, etc. These are procedures that must be performed when the system is shut down, not optional. A forced shutdown may result in data loss, system damage, partition table loss, or even hard drive damage.

Treatment method: The general solution can be to press f8 after booting, choose to use "Safe Mode" or "Last Known Good Configuration" to log in to the system, and repair the bad files or registry.

If it doesn’t work, enter the recovery console to repair it. Insert the system installation CD and set it to boot from the CD-ROM drive. After a period of initialization, a prompt operation interface will appear. Press R to enter the console. Enter the operating system number to enter the corresponding console. At this time, the system will prompt you to enter the password, which is the Administrator account password. Use the chkdsk command: chkdsk is the most commonly used disk maintenance tool. You can use chkdsk to check the logical and physical errors of the disk and repair them. If files are missing during startup, you can use the expand command: you can extract files from a compressed package or compressed file. This command is very useful. It can be used to extract the correct files from the Windows installation CD or other installation locations to overwrite the erroneous files in the system. If a system file is lost, the file location and file name will usually be prompted. All you need to do is to remove the last character from the file extension and add an underscore to get the corresponding file name in the installation CD, and then use the expand command to correct the file name in the installation CD. The files are decompressed to overwrite the damaged files, thus achieving the purpose of repairing the system. If there is a problem with the boot record, you can use the fixmbr command: Repair the master boot record of the startup disk.

If it still doesn’t work, it is recommended that the user reinstall the system, turn on the computer and press the esc key, insert the system installation CD, boot from the CD, and install the system.
