Another diagnostic / possible help thing to try (though if a CPU really is switching off, it's probably time for drastic measures) are Apple's CHUD tools: http://developer.apple.com/tools/download/ When you have these, you'll be able to add a 'Processor' pane to your System Preferences. Within the Processor pane you can view the activity of both CPUs in neato graphs which are more fun than those in the Activity Monitor, and more impressively you can manually turn the 2nd CPU on and off. You can also toggle the computer's napping capability on/off, which has proved in some cases to help suppress weird noises made by some people's G5s. ----------------------------------------------------------------- Group Buy until Feb 22nd for Virtual Instruments Magazine!
