Hi guys. First post and as well as first mac so be patient on this one. Also i tried the search function and google but nothing helping on this. I got a iBook G4 recently and have no idea really what i'm doing outside what i've read online. These are the symptoms: Normal start-up: Start-up sound, a folder with a question mark shows up for a second after the folder with the mac face on it and then goes to the white background with the gray apple on it then shortly there after the spinning wheel comes up and it will either freeze there or will go to a blue screen and freeze there. Safe-boot: Hold down shift when i hear the start up noise continues start up no indication of safe-boot at all. Freezes at white background with gray apple shortly after the spinning wheel shows up. Single user command: I enter the command line for "fsck -fy" and it will go all the way to ** Checking Catalog File and stop UNLESS i insert a random cd and then it will go to ** Checking Catalog Hierarchy and stop I've reset the PRAM and PMU multiple times with no success. Also after several failed attempts the computer will start giving me the "rainbow screen of doom" or whatever its called. I've tried removing the additional RAM to see if it was bad but it acted no different. I also got this computer from my girlfriend and she lost all the OSX discs. I have access to the dmg files for all 4 Panther discs though. Is there anything i can do or anyone know whats wrong? I don't have access to another mac only this pc. I do have a 30g ipod i can copy the dmg files to and also a cd-r burner so i can burn the files to discs if that will work but i read you cant really make a bootable osx disc with a pc. I really have no clue so any help is appreciated. I really need it back up and running so i can work on music. Thank you in advance.
