Hi there and welcome to PCHF.
The message is probably referring to your Windows Virtual memory. To increase it do this:
How to change the size of the virtual memory paging file
You must be logged on as an administrator or as a member of the Administrators group to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
1.Click
Start, click
Run, and then type sysdm.cpl in the
Open box.
2.Click the
Advanced tab, and then click
Settings under
Performance.
3.Click the
Advanced tab, and then click
Change under
Virtual memory.
4.Under
Drive [Volume Label], click the drive that contains the paging file that you want to change.
5.Under
Paging file size for selected drive, click
Custom size, type a new paging file size in megabytes (MB) in the
Initial size (MB) or
Maximum size (MB) box, and then click
Set.If you decrease the size of either the initial or maximum paging file settings, you must restart your computer to see the effects of those changes. When you increase the paging file size, you typically do not have to restart your computer.
Notes
•To have Windows select the best paging file size, click
System managed size. The recommended minimum size is equivalent to 1.5 times the
RAM on your computer, and 3 times that figure for the maximum size. For example, if you have 256 MB of
RAM, the minimum size is 384 MB, and the maximum size is 1152 MB.
•For best performance, do not set the initial size to less than the minimum recommended size under
Total paging file size for all drives. The recommended size is equivalent to 1.5 times the
RAM on your computer. It is good practice to leave the paging file at its recommended size. However, you may increase its size if you frequently use programs that use much memory.
•To delete a paging file, set both the initial size and the maximum size to zero, or click
No paging file. We strongly recommend that you do not disable or delete the paging file.
