Occasionally you may have problems while working with your iMac G5. This chapter gives you some solutions to try when you have a problem.

This chapter contains solutions to problems that prevent you from working with your computer, such as a system freeze or a computer that will not start up. You can find more troubleshooting information in Mac OS Help (see page 22), on the Apple Support website at www.apple.com/support, and in the Apple Knowledge Base at kbase.info.apple.com.

When you experience a problem with your computer, there is usually a simple and quick solution. When you encounter a problem, try to make a note of things you did before the problem occurred. This will help you narrow down the possible causes of the problem and then find the answers you need. Things to note include:

•The applications you were using when the problem occurred. Problems that occur only with a specific application may indicate that the application is not compatible with the version of the Mac OS installed on your computer.

•Any software that you recently installed. Certain applications install extensions that may not be compatible with the Classic environment.

•Any new hardware (such as additional memory or a peripheral) that you connected or installed.

Problems That Prevent You From Using Your Computer

If the computer won’t respond or the pointer won’t move

•First, make sure the mouse and keyboard are connected. Unplug and then plug in the connectors and make sure they are secure.

•If that doesn’t work, try to force problem applications to quit. Hold down the Option and Command (x) keys and then press the Esc key. If a dialog appears, select the application and click Force Quit. Then save your work in any open applications and restart the computer to be sure the problem is entirely cleared up.

•If you are unable to force the application to quit, press and hold the power button (®) on the back of the computer for a few seconds to shut down the computer.
