When the game is running, it means that the computer hardware is aging, the performance is declining, or there is conflict between the hardware, and the hardware performance is close to or very close to the threshold for calling out the game.

As for bouncing back to the desktop, consider this:

Consider whether there is a problem with the graphics card driver, whether it is the latest driver, and whether DX software is installed.

Considering the conflict and incompatibility between the system and the game, if it is WIN 10 system, it is recommended to switch to WIN7, because 10 is always in conflict, and many players will flash back when using WIN 10.

Close all unused background software, including software that starts automatically when it is turned on, and close software that takes up a lot of memory resources to save memory space.

To clean the dust in the computer case, you can use a hair dryer and an exhaust fan. After cleaning the dust, the hardware performance of the computer can be slightly improved.
