How to Fix Computer Low on Memory in Windows 10

As the need for multitasking increases in an ever-busy IT world, running multiple applications concurrently has become the norm.

Some applications demand a lot of "free memory" to run efficiently because of the high demand placed on the CPU. Such software applications include Graphic design and video editing applications such as Adobe Photoshop, Adobe Premiere, and gaming software.

These applications hog a lot of RAM or main memory and since RAM is finite, it gets depleted forcing the system to turn to virtual memory. When virtual memory gets over-utilized, the system triggers a "Low on Memory" warning notification indicating that you are running low on virtual memory.

Many users reporting this kind of problem are known to use Windows 10 as their choice operating system. Since this error leads to slow computer operations, the best thing to do is to transfer some of the used memory pages to another system file by the name pagefile.sys. This hidden file is found in the root directory and you can use it to allocate more RAM space for quick machine operations.

What causes the Computer is Low on Memory Error?

The error is quite bothersome especially when you are running a program that needs a lot of free space. The best advice you can get from this article is not to rush to purchase an extra RAM yet the problem could be a software issue. Some of the causative factors include:

1. Running many Processes

Processes that consume a lot of space available on the memory leaving no space for other programs will lead to this error. This happens when so many programs are running at the same time. When your windows machine encounters many program instructions, it will transfer some to the virtual memory (a process known as paging). The best way to avoid such scenarios is to reduce the number of running programs.

2. Junk Files Occupying Space

Computer’s system registry always stores program information on RAM over time. When the number of information stored increases, they end up using part of the RAM. The best solution to this is using the Disk Cleanup Utility to delete all junk files.

3. Low Virtual Memory

When the virtual memory is used past its limit, this error is inevitable. It implies that the system can no longer handle any more processes and memory needs to be freed up.

4. Having Too Many Installed Programs

If the number of programs installed on the computer does not leave enough space to allow for startup applications, you are likely to encounter this error. The reason behind this is due to RAM overload, which can be solved uninstalling the software, or programs that are rarely used from the computer.

All these problems will undermine the ideal performance of your computer which will leave you frustrated. Some simple things such as opening multiple tabs in a browser while performing several tasks simultaneously may also lead to computer low on memory error.
