If you have multiple applications open at one time, consider closing all non-essential applications. Click Task Manager to see a list of applications currently open. To find out how much memory an open application is using, check the Memory tab of the System Information utility.
If this problem occurs often, consider upgrading either your video card or your Central Processing Unit (CPU). To find out what is currently installed in your computer, open the System Information utility and use the System and Display tabs.
