Lets say you are running a application like Adobe Photoshop and while you are rendering a big sized image the pc starts using high amount of RAM and when there isn’t any adequate Random Access Memory on your PC which can handle processing of this data. This is when the PC starts using the Virtual Memory.
Temporary storage used by a computer to run programs that need more memory than it has. For example, programs could have access to 4 gigabytes of virtual memory on a computer’s hard drive, even if the computer has only 32 megabytes of RAM. The program data that does not currently fit in the computer’s memory is saved into paging files.
Finding Source of Low Virtual Memory Problem :
In order to quickly solve this problem you need to first find the source of it by checking out the Task Manager and analyzing all the programs to find which one of those is using the highest memory and closing them. This way you can close the programs which you are not actively using and those which use high amount of your memory.
