My iMac G5 has been-- satisfactory. Sure, the fans get a little loud, and those Intels that my family is surrounding me with do make me a little jealous, but today, it's gone too far. I got an HV20 for Christmas, which is great because it's my first HD camera and I've wanted one for a while now, and so I recorded just some simple footage of my dog as well as me saying some stuff, and then it was off to Final Cut Pro. Before, with my kiddie cameras, I'd use iMovie to import because Capture Now never worked with them. Today, I decided that I'd use Capture now, and it worked, after reconfiguring Easy Setup. Over time, I noticed that my G5 finally went off the edge and started blaring and couldn't do the simplest of tasks. I could switch between Spaces and windows and stuff, but, for example, I elected to open the Force Quit window, and it didn't appear for five minutes. That's not an exaggeration. I decided to close everything and restart, but it played this game with me where the "Are you sure you want to restart? If you do nothing, it'll automatically restart in XX seconds", and I'd of course press Restart, but it wouldn't restart. I had to press on the power button to turn it off, and I had to press it several times again before it would start up again. After booting up, it still is slow, and I couldn't even repair permissions or anything. What's wrong with it? How can I make it faster? It's been fine until now! What can I do? Thanks!
