If it is a sudden and serious jam, you need to check what you did before the jam appeared, such as downloading and installing software, installing drivers, browsing some unsafe websites, determining the reasons, and then uninstalling the installed software and drivers according to the right medicine. There is a very important reason here, that is, when browsing some websites or downloading and installing some software, many related software and games will be automatically downloaded and installed at the same time. These are all maliciously installed by some rogue software and websites, which is very annoying. You need to find all of them and uninstall them. After all, restart the computer to check whether the stuck problem has been solved. If you haven't done obvious operations, or don't know what operations you have done, you may be infected with the virus. You can use antivirus software or security guards to do antivirus. Then check the installation time of the software program, find the software installed the day before the system is stuck, and uninstall it. It should be noted here that two or more antivirus software developed by different companies must not be installed at the same time, such as 360 and Kaspersky or Kingsoft Internet Security, and only one can be installed, for the reasons explained in the previous article.
