Got my Dual 2.0 G5 about 3 months ago (actually exactly 93 days...3 days out of phone support) and everything was fine and dandy in my world. And one day there was a kernel panic (screen turns gray, gives you the big message in several languages about having to restart). No big deal. And another one, and another. And sometimes the entire interface would lock up except the mouse (can't interact with any applications, and the time doesn't change in the menu bar). I figured out the problem with that was the WindowServer process somehow locked up. I could fix that by getting into the G5 through SSH and to kill the process, it would log me and out and it would be fine. And now its getting worse, applications are randomly quitting (not coming up with the message that they unexpectedly quit), OS X randomly reboots (I've come back to the login screen 5 times in 24 hours), and as if it's not acting enough like a Windows box - sometimes when applications decided to quit themselves, the window is still on the screen until that part of the screen is updated/refreshed (I never had that on OS X, I thought that was an advantage of Quartz). My machine is Dual 2.0 G5, 1GB RAM, 160GB HDD, Airport Extreme. This is the latest revision that came out around May. I have done a format/reinstall, but I ran Migration Assistant to import my account, library, and applications. I might try a reinstall again today when I get home from work. This is my plea for help, guys!
