ct an external hard drive to your computer and set Windows to use it as virtual memory.
Click the “Start” menu, right-click “Computer,” click “Properties” and click “Advanced system settings” on the left side of the window. Enter the Administrator password if prompted.

Click the “Advanced” tab. Click “Change” near the bottom of the window.
Un-check the box next to “Automatically manage paging file size for all drives.”
Select your external hard drive from the list. Click “System managed size” to allow your computer to allocate virtual memory on the hard drive. If you want to set a customized virtual memory size, click “Custom,” type a minimum and a maximum for the memory size and click “Set.” Click “OK” and restart your computer.
