Hi all,
I regularly get the message that the virtual memory is too low. What is virtual memory and is there anything I can do to prevent it happening in the first place?
Thanks Richard.

Virtual memory is a section of your hard drive that is used as an overflow pool for your RAM. This article should help you understand it better and maybe fix it:
