Troubleshooting with iMac G3 Slot-Loading 350 Hz Indigo 

If you don’t find the answer to your problem look in Mac Help, where you can find a great deal of troubleshooting advice, including information to help you solve problems with connecting to the Internet, using software installation and restore discs, System performance, turning extensions off and on and more. Just choose Finder from the Application menu, then choose Mac Help from the Help menu. Look at the section on preventing and solving problems, or type the problem you’re having in the search window (for example, type “I can’t eject a disc”) and click Search.

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

  • Make sure the mouse and keyboard are connected.
  • Unplug and then plug in the connectors and make sure they are secure.
  • Try to cancel what the computer is doing.
  • Press the Command (x) and period (.) keys at the same time. If a dialog box appears, click Cancel. If that doesn’t work, hold down the Option and Command (x) keys, and then press the Esc key.

If the computer still doesn’t respond, restart it:

  • Hold the Power button on the computer for several seconds. When the computer turns off, press the Power button again to restart it.
  • If that doesn’t work, press the Reset button. If that doesn’t work, unplug the power cord from the computer. Then plug the power cord back in and press the Power button on the computer to turn it on.

Then do this:

If the problem occurs frequently when you use a particular application: Check with the application’s manufacturer to see if it is compatible with this computer.

If the problem occurs frequently whatever application you use: Choose Mac Help from the Help menu. Look at the section on how to prevent and solve problems. You may need to check for extension conflicts or reinstall your computer’s system software.

If the computer “freezes” during startup or you see a flashing question mark:

Turn off system extensions: Start up your computer while holding down the Shift key.

If that doesn’t work, start up using the software install CD: Insert your software install CD and start up while holding down the C key. (Make sure the Caps Lock key is not engaged.)

Then do this:

After the computer starts up: Make sure that the hard disk that contains the System Folder is selected in the Startup Disk control panel. Choose Mac Help from the Help menu. Look at the section on how to prevent and solve problems. You may need to check for extension conflicts or reinstall your computer’s system software.

If you notice that the background picture is different: You probably started up your computer using the system software on a CD instead of your hard disk. If this is the only way that you can start up your computer, reinstall the system software on your hard disk. Look for instructions in Mac Help or use the Installer application on your software install CD.

If the computer won’t turn on or start up:

  • First, make sure the power cord is connected.
  • Make sure both ends of the power cord are plugged in securely.
  • Make sure the power cord is plugged into a working electrical outlet.
  • If your computer is plugged into a power strip, make sure the power strip is turned on.

If that does not work, reset the computer’s PRAM memory: Start up the computer and immediately hold down the Command (x), Option, P, and R keys until you hear the startup sound a second time. After resetting PRAM, you may have to reset the settings in some of your control panels.

If that doesn’t work, or if you hear several musical tones during startup:  If you recently installed additional memory, make sure that it is correctly installed and that it is compatible with your computer. See the service and support information that came with your iMac for information on having your computer serviced.
