This means that the process in your system has not been loaded. If too many processes are started, the machine may slow down or crash. If your notebook has been waiting for a long time, the mouse arrow menu is still blank and you can't enter the system. Then I suggest you reinstall the system. If you can get in, please follow the following steps to have a try. If it still doesn't work after restarting, I suggest you redo the system:

Steps:

1, check the system antivirus operation;

2. Clear some useless startup items.

(1) Please enter "msconfig" in Start-Run and press enter;

(2) Select the "Start" tab;

(3) In the "startup items" below, uncheck the box in front of the startup items that don't need to be booted under the "command" column; Then click OK to restart the computer (for example, startup items that don't start with "c:" don't need to be started).

(4) After startup, a big prompt box will pop up on the desktop. Please check the "Don't prompt" check box below this box (I can't remember exactly what it is here, anyway, just don't let him continue to display it next time), and then confirm;
