Fix Your Computer Is Low On Memory Warning [SOLVED]

Your Computer Is Low On Memory warning happens when Windows has run out of space to put the data it needs to store when you’re running different applications. This can be either in the RAM modules in your computer, or also on the hard disk when the free RAM has been filled up.

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

When your computer doesn’t have enough memory for all of the actions it’s trying to perform, Windows and your programs can stop working. To help prevent information loss, Windows will notify you when your computer is low on memory.

Fix Your Computer Is Low On Memory Warning

Your computer has two types of memory, Random Access Memory (RAM) and virtual memory. All programs use RAM, but when there isn’t enough RAM for the program you’re trying to run, Windows temporarily moves information that would normally be stored in RAM to a file on your hard disk called a paging file. The amount of information temporarily stored in a paging file is also referred to as virtual memory. Using virtual memory—in other words, moving information to and from the paging file—frees up enough RAM for programs to run correctly.

Your computer is low on memory warning occur when your computer runs out of RAM and becomes low on virtual memory. This can happen when you run more programs than the RAM installed on the computer is designed to support. Low memory problems can also occur when a program doesn’t free up memory that it no longer needs. This problem is called memory overuse or a memory leak.

Fix Your Computer Is Low On Memory Warning

Before moving to the below-listed advanced tutorials, first, you can kill the programs that are using too much memory (RAM). You can use Task Manager to kill these programs which might be utilizing too much CPU resources.

1. Press Ctrl + Shift + Esc to open the Task Manager.

2.  Under the Processes tab, right-click on the program or process utilizing the most memory (will be in red color) and choose “End task”.

If the above doesn’t fix the Your Computer is low on memory warning then in order to prevent such warnings, you can change the minimum and maximum size of the paging file by following these steps.

Method 1: Increasing Virtual Memory

Now the more the RAM size (for example 4 GB, 8 GB, and so on) in your system, the faster the loaded programs will perform. Due to the lack of RAM space (primary storage), your computer processes those running programs slowly, technically because of memory management. Hence a virtual memory is required to compensate for the job. And if your computer is running low on memory then the chances are that your virtual memory size is not sufficient enough and you may need to increase virtual memory in order for your computer to run smoothly.

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

  1. It said the changes I made require me to restart computer in order for them to take effect. Does this mean I decreased the memory size? If so..isn’t this the opposite of what I was trying to accomplish since I have already been getting memory message pop-ups. I followed this article to a “t” please help ! Thanks

  2. Thank you. It worked…sort of. Chose Method 1, went to “Performance Options” and under “Visual Effects” I changed from “Custom” setting to “Let Windows choose what’s best for my computer.” (I didn’t go into “Advanced” settings because that would have required me to make a change in “Virtual memory” and I’m not into that). But the change worked and boosted my available memory from 5-10% to 55-60%. However. when I went back to re-check the settings later, the “Visual Effect” setting had changed back on its own from “Let Windows… to “Custom.” I think I need new spark plugs.(I’ll get my coat)

  3. I was able to increase available memory on c drive from 40MB to 623MB using 3 of the 4 tips recommended here. Only took me about 35 minutes. Thank you!

  4. I had less than 1GB left out of 465GB SSD. After following the first step I got back 10GB, then the second I got back an additional 165GB! Outstanding!

  5. Anyone have this problem ? Anytime I start a game is crashed with this error. I’ve tried everything. Please help :} Thank you. Out of memory (requested-1430938 KB) footprint 218798971 KB.
