Here are a few steps to free up RAM on your computer:

1. Close any programs you’re not using, if asked to 'Save' your work before closing, select ‘yes’ or ‘save’.
2. Open Task Manager by pressing ‘Ctrl+Alt+Delete’ and go to the 'Processes' tab.
3. Scroll through the list and identify which applications are using most of your RAM.
4. Select the application or process and click ‘End Process’ to free up RAM.
5. Repeat steps 3 and 4 until you’ve free up sufficient RAM. Think about putting any software you no longer use on 'sleep' or 'hibernate' if possible.
