“Your computer is low on memory” appears on Windows 10/8/7? Why is the computer running low on memory? How to fix the low memory error? This post will show you much information about the error and offer you full solutions to get rid of trouble.

Computer Says Low on Memory Windows 7/8/10

When using your computer, Microsoft Windows may show you an error message:

Your computer is low on memory
To restore enough memory for programs to work correctly, save your files and then close or restart all open programs.

your computer is low on memory warning

Or Windows prompts you “Close programs to prevent information loss. Your computer is low on memory. Save your files and close these programs.” The issue occurs when you open Outlook 2013, a large-scale game, or any program.

When you receive the low memory error, it means that your computer is running out of RAM and becomes low on virtual memory. Why is the computer low on memory? That’s because some programs on your computer take too much allocation of memory. 

Tip: The items of RAM and virtual memory are totally different from disk space. RAM is physical hardware inside your computer and installed when buying your system. Virtual memory refers to a memory management technique that is implemented using both hardware and software.

You should know, the low memory issue can happen when you run more programs than the RAM installed on the computer is designed to support. And this issue can also occur when a program doesn’t free up memory that it no longer needs. We call this memory overuse or memory leak.

If you are bothered by the computer running out of memory issue, what should you do to get rid of trouble? Just go to the next part to get the solutions.

Note: Some of you report in Reddit that when the alert appears, the PC memory actually works correctly. It seems that the computer somehow misinterprets various memory indicators (e.g. 16GB RAM is only half used but the warning still occurs).

Then, your problem will likely go away.

Doing this will increase the paging file size and add the virtual memory of the system. Just go to check if computer low on memory is fixed.

In addition, if you have tried the above 3 methods but “your computer is low on memory” warning still appears in Windows 10/8/7, the only thing you can do is to add physical memory or upgrade your RAM. In the following paragraphs, we will show some details.

Way 4: Upgrade RAM or Add a New Memory

As with the most thing about PC upgrade, you need to figure out what you need. By contrast, it is a breeze to install your memory physically.

Generally speaking, more RAM is better but now we recommend at least 8GB of RAM for most of you. This is a kind of the sweet spot. If you are a gamer, or you need to perform lots of bigger programs, 12-16 GB is suitable.

Besides, before installing new memory, you should know how much RAM your computer can handle. This is based on the versions of Windows and the motherboard. What’s more, you need to determine what type of RAM your computer is able to use.

All these are important things that you should pay attention to, otherwise, the new memory is not compatible with your computer. Then, you can open your computer case and install the new memory to the slot. For more information about how to upgrade or replace your RAM, you can read the help document from howtogeek.

Later, you can go to Settings > System > About to check out the amount of recognized RAM. By this way, “your computer is low on memory” can be fixed completely.

Important: There is a special situation that you should notice. For 32-bit versions of Windows 10, it can only handle up to 4GB of RAM whether you are running Home, Professional or Enterprise edition (usually, you’ll only be able to access around 3.2GB).

This is because of memory addressing limitations. And the same situation also happens on Windows 7 32-bit. But with a 64-bit OS, you can have full access to the whole 4GB.

Therefore, if you add a new memory or upgrade your RAM in Windows 7 and 10 32-bit, you still cannot use the redundant memory. To let the rest of the memory work, you need a 64-bit system. If you use a 32-bit system of Windows 7 and 10 previously, you need to reinstall the system and install a 64-bit one.

Tip: Before installing a 64-bit system, you had better back up your important files since the reinstallation can cause data loss. To do this work, a piece of backup software is needed.

Back up Important Files before Installing 32-Bit OS

In order to easily back up crucial files, Windows backup software, MiniTool ShadowMaker, is worth recommending. As a professional and reliable backup program, this tool can help you to back up files, OS, disk, and partition to an image file within simple clicks. To use the files in case of data loss, you need to perform a restoration.

Besides, it can help you to sync files to another location to keep data safe. When locating the path, you can directly use the files. Just get MiniTool ShadowMaker from the button below and install it on your 32-bit system to start a file backup.
