Analysis: The computer can be restarted after the blue screen. If the screen is still blue or you can't access the system, you need to reinstall the system.

Treatment: It is recommended to use the CD reloading system, and its operation steps are as follows:

(1) Prepare the system CD: If there is nothing to buy in the computer shop, buy the latest CD of any system that needs to be installed. If you have a CD-ROM drive, you can also download the system files in ISO format and burn them to the system CD.

(2) Set the CD-ROM to start: press the DEL key (usually F2 for notebooks or hotkeys prompted according to the bottom line of the screen) to enter CMOS, and set the CD-ROM or DVD-ROM as the first startup item in the BOOT tab (after the old motherboard needs to enter the advanced BIOS function tab, press Enter at "1st Boot Device" and then select CD/DVD. Insert the system CD into the CD-ROM drive in time when restarting the computer.

(3) Clone installation system: After the CD is successfully started, the function menu will be displayed. At this time, select "Install the system to the first partition of the hard disk" in the menu, press the prompt after entering the PE system, or run the "One-click Installation System" on the desktop, and the computer will automatically run GHOST software to automatically load the GHO file and clone it to the C area. The whole process basically does not require human intervention until it finally enters the system desktop.

Note: After installing the system, first install 360 security guards and 360 antivirus or Kingsoft Internet Security software to thoroughly kill Trojans and viruses, then patch the system, install common software, download and install one-click restore tools for emergencies.
