Often computers forget how to start up CDs automatically when you put them into the drive or they start up in the wrong program starts up.
To solve this problem go through the following steps:
1. Close any programs that are running.
2. Double-click on My Computer (on your desktop or in the right pain of your XP start menu).
3. Right-click on your CD-ROM icon.
4. Click on Explore from the menu that comes up.
This will open up a window showing the contents of the disk. From this point you can click on the "Setup" icon if you are trying to install a program. If the disk contains pictures or music, double click on the files that you want to look at or listen to.
