What is the specific situation? If it's only for a moment, only a few tens of seconds, then your computer system is a bit slow. It may be used for a long time, and this will happen. This usually happens when you just turn on your computer, or after you open a web page and turn it off, or after the software is turned off. If there is no response for a long time, your computer will crash. Restart it. If you have to wait a second, I suggest you. (* _ _ *) Hee hee ...
