This normally happens when your RAM fills up. What you can try to do is increase the size of your “Paging file” (it should normally be twice as size of your RAM) but more can save you better in some cases. As a short description: Paging file supports your RAM and when the RAM fills up the rest of the data is being stored there to prevent lack of memory. Surely try the control points as well but try to adjust the paging file too. It is easy to search on the internet, nothing too complicated.
