The system discs included with your iMac G5 have a utility that you can use at any time to verify that your computer's hardware is working properly. If you are trying to diagnose a computer problem without contacting technical support or simply want to verify that all is right with your computer before selling or giving it away, use the Apple Hardware Test on your Mac OS X installation DVD to test your computer's logic board, memory, hard drive and other components.
Things You'll Need
- Mac OS X installation DVD (Disc 1)
Insert the Mac OS X installation DVD while your iMac G5 is running. If the installation utility loads automatically, close it.
Click the Apple menu in the upper-left corner of the screen, and then click "Restart" to restart your iMac G5.
Push the "Option" key on the keyboard immediately after the iMac G5 begins to restart. Continue holding the key until a set of icons appears on the screen and the computer waits for you to choose a startup volume.
Press the right-arrow key until the "Apple Hardware Test" icon is highlighted, and then press "Return." After a moment, a new screen titled "Apple Hardware Test" appears and the mouse becomes usable.
Click the "Quick Test" button to run a short test of your computer's hardware, or click "Extended Test" to run a full test. The Quick Test requires five to 10 minutes to complete, while the Extended Test requires five to 15 minutes. Run the Extended Test multiple times if you believe that your computer has an intermittent hardware problem that might not reveal itself during the first test session.
