Sometimes the computer will suddenly jump out of the pop-up window, prompting that the system is out of memory. This situation is sometimes caused by opening a software, and sometimes doing nothing.

1. First, right-click my computer-click Properties.

2. Click Advanced in the System Properties tab, and then click Settings under Performance.

3. In the pop-up performance tab, click Advanced.

4. Finally, click the virtual memory change at the bottom, set the virtual memory to a reasonable value in the dialog box that appears, and then click OK. If it is displayed. When the virtual memory is large enough, there will be no pop-up window with insufficient memory.
