Ok so I am still getting used to the world of Mac so please bare with me. I originally started out with this machine that would boot to a screen with a folder and a question mark. I tried loading from the cd just to do a fresh install but after the apple symbol with the spinning wheel all I get ais a blue screen that never goes anywhere almost like its trying to load the GUI for the cd but it can not. I tried a few different hard drives and changed out the memory. Some of these hard drives mind you were from windows machines and I didn't think formatting any of them would matter. (I assume disk utility would do that for you?). I am still getting a blue screen. Sometimes its a darker blue sometimes its a lighter blue. I attempted to boot into verbose..it loaded up fine and then kicks me back to the blue screen. I can boot into safe mode fine but not a clue if I can load the cd properly from there. Everything appears to be working.. I can choose a bootable partition with options key. I can boot into safe mode and verbose mode. I hear the chime. I see the logo with the spinning wear on the grey background. But then a never ending blue screen pops up when I load from the cd. Tearing my heair out.
