Ok, so I am a High School mac-addict. I am taking a computer maintenance class this year, and I was given ANCIENT macs to work on, (I'm the only one allowed to work on them, [the teacher likes me]) And I finished all my work early one day, and I asked if I could look at the old iMac in the corner of the room, and or course, the teacher said yes. So i proced to look at it, and hook up the keyboard, and mouse, and plug it in, it chimed (YAY) but the light on the power button stayed orange (Booo!) so I played with it, gave it a lil' shake, (nothing to big, just a lil' wobble) and tried turning it off and on multiple times. I finnaly got the button to glow green (Yay) but the screen would not come on (booo!) and it was making a clicking type noise toward the middle, to the back area, (Booo!) I told the teacher that I thought it could be Arching, or something, and after lots of talking, and emails back and forth I was told that If I could get it to work, that for all my hard work that I could keep it, and take it home!!! YAY!!!! So, my question, what are the possibilities that could be wrong with it, it is I think a Rev.A and it looks just like it came out of the box, NO JOKE, I would really like to fix it. And maybe after that, I can talk him out of his Mac Plus.... does anyone know where to get an original boot disk for one of those by the way? ALL HELP IS EXTREMELY APPRECIATED!!!!!!
