Computers have two types of memory, namely random access memory (RAM) and virtual memory. When the program occupies too much memory space and does not release it, the system will prompt that there is not enough memory. Insufficient memory can lead to poor performance, insufficient memory notification and display problems. Solution:

1. Increase the size of the page file (virtual memory). (My Computer-Properties-Advanced-Settings-Advanced-Change-Select Drive-Custom Size-Settings)

2, install RAM (that is, buy a memory stick and install it. )

3. Determine whether the program uses too much memory (open Task Manager to see which programs use too much memory. If the program is closed, it means that the process has not been closed, and you can end the process to release memory space).

4. use software to cc cclean.
