In the past the only way to avoid this type of issue is to either run less programs at the same time or buy more memory and install it. Since writing and reading to a hard drive is much slower than reading from physical RAM, your computer's performance takes a huge hit.

Have you ever had an experience where you are using a lot of programs in Windows, or a really memory intensive one, and notice that your hard drive activity light is going nuts, there is lots of noise from the hard drive, and your computer is crawling? This is called disk thrashing and it is when you have run out of physical RAM and instead Windows is using a file on your hard drive to act as a virtual memory.
