Fix 'Your computer is low on memory' and Cleanup Computer Memory on Windows 10/8/7

Updated on Apr 04, 2019 by Jean to Backup and Recovery

This page deals with 'your computer is low on memory' issue on Windows 10/8/7 when it is real and not real. When your computer reports the insufficient memory error for opening files or running programs, read this post and find the suitable solutions to either free up some computer memory or increase vitual memory.

All solutions to "Your computer is low on memory" on Windows 10/8/7:

Solution 1. Kill the program that is using too much memory
Solution 2. Increase the Virtual Memory
Solution 3. Upgrade RAM without reinstalling Windows

Basic knowledge of Memory:

In Windows 10, the error message reads as "Your computer is low on memory. To restore enough memory for programs to work correctly, save your files and then close to restart all open programs."

In Windows 7, it reads a little different but suggests the same problem "Close programs to prevent information loss. Your computer is low on memory. Save your files and close these programs."

When you receive "Your computer is low on memory", it means that your computer runs out of RAM and becomes low on virtual memory. The items of RAM and Virtual Memory are totally different from the disk space of hard-drives or removable storage devices, and you can google that. Anyway, to resolve the warning memory issue, you can clear memory and increase RAM. If the first two methods fail, it's time to upgrade your computer RAM. 

Solution 1. Kill the program that is using too much memory

Some processes using too much memory would probably throw you the exact low memory error on your computer. In fact, the following way of ending the process that is using too much memory in the Task Manager is very useful when Windows OS is with high RAM or CPU usage issue.

Step 1. Press "Ctrl + Alt + Del" to bring up a menu and choose "Task Manager".

Step 2. Under the Process tab, you'll clearly see which process is using the most memory. Right-click the process's name and choose "End task".

Solution 2. Increase the Virtual Memory

If the first solution only solves your problem in a short period of time, then increasing the Virtual Memory should be recognized as a long-term fix.

Step 1. Press "Windows + R" and type sysdm.cpl in the Run dialog box and click "OK" to open System Properties.

Step 2. Click "Advanced system settings".

  • Click "Set" and "OK".

Solution 3. Upgrade RAM without reinstalling Windows

Among all the suggested solutions on this page, the final solution to upgrade RAM is 100% working in resolving the computer running low memory issue. Especially when your computer constantly warns you that it's on low memory issue even it's really not, it's time to replace your RAM then.

Step 1. Boot your computer from EaseUS Todo Backup bootable USB flash drive.

Step 2. On the main window of EaseUS Todo Backup, click "System Transfer".
