My computer is a Dual 2.0 G5 running OS10.3.5. Here's what happened: I was dragging/duplicating an image file into another folder. When I saw it was a 200mb file I realized it was the wrong one so I pushed the "stop" button. At that moment everything froze up except the mouse and the clock. I gave it a couple minutes to see if the computer would come out of it then decided to restart. The keyboard was not responding so I held in the power button on the front. When it restarted the screen flashed blue a few times, I heard some strange "clunking" noises, then the flashing ? folder came up. So I tried starting from the disk that came with it, I held down Option to get to the hardware checker program. After like 20 minutes it said my computer was fine. When I start up from the same disk and hold C, it only gives me the option of installing OSX. And I can't find my hard drive when it asks me the destination. Any ideas? Anything I should try? I'm kicking myself in the ass that I didn't get Applecare right about now. Thanks!
