I've got a G4 here at work and last week I loaded Tiger onto it. Earlier this week, it locked up and I could hear through my headphones a short static noise that repeats over and over. So I hit the restart button. When OSX came back after logging in, it would stall when trying to load the menu bar. It got as far as the spotlight icon, but nothing else. I could hear the hard drive working for a bit, then nothing. So I moved the mouse over the Spotlight icon and I get that rainbowy circle that spins. Tried shutting down & restarting all with the same effect. So I re-loaded Tiger and just now it did it again. I use Synergy with iTunes and I dunno if that's the cause, or even a ballpark of what the cause is. Any ideas? This is super frustrating.
