Virus detection
Before checking whether the laptop hardware is loose, we need to scan the hard disk with anti-virus software to see if there is a virus lurking. If a virus is found, it needs to be removed quickly to avoid more damage to the computer.

Back up all drivers, especially network card drivers. This can quickly restore the normal use of the computer after reinstalling the system. If there is no driver CD, you can download the corresponding driver from official website according to the notebook model.
Reinstall (a computer) system.
Prepare to reinstall the system. Before reinstalling, it is recommended to back up the original system and make clone files. After reinstalling the system, don't click on any disk other than disk C for the time being. Connect broadband, download an antivirus software, such as Kingsoft Internet Security, and conduct a comprehensive inspection after installation to ensure that the computer is virus-free.
Drive installation
It is sometimes troublesome to install a driver for a notebook. If you don't have an optical drive, you need to download the corresponding driver from official website according to your notebook model.
