Question about Apple Power Mac G5 Desktop
My G5 mac desktop freezes at random, everything sticks and the red light comes up front comes on, and the fan come on full blast. I half to push the button on front to shut it off. Any ideas
First you need to run some maintenance (which in itself may solve it) to rule out software issues, so start here...
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
Mac OS X: How to start up in single-user or verbose mode
If that doesn't help, try booting into Safe Mode and see what happens, if it comes up hopefully another restart may solve, if not, you can at least use this as a starting point to try and resolve. Safe Mode will allow you to get around, surf, etc...
What is Safe Boot, Safe Mode?
Mac OS X: Starting up in Safe Mode
If Safe Mode comes up alright, I would install AppleJack, excellent troubleshooting article can be found here... Troubleshooting Tools: AppleJack
Another excellent free tool for performing maintenance is Onyx (be sure to download the right version for your system). Install the package, then run it, it will check your drive and the structure, after this, click on the automation tab and check on everything for Maintenance, Clear Cache, Cleaning, and check on Reset -> LaunchServices database and Mail's Envelope Index. When it completes, restart. Repeat any time something seems flaky, if not try to run at least once a month.
