Always list your system specs when asking for help, including your OS.
In this case virtual memory is probably your page file. This is a place where Windows stores some things it needs on your hard drive. If your hard drive is getting too full, windows runs out of space for the pagefile.
Delete some unused files from your computer and the problem should go away.
