I have a problem with my ibook g4 bought in 2005. I am just about to sell it for a good price, and the day after i receive half the money as a deposit, it decides it doesn't want to go past the blue screen in which it says 'starting osx' the blue loading bar loads fully, then it does nothing. i can move the cursor around etc but nothing else. i have left it over night and still stuck on that screen. Also, there is a music cd in the slot so i cant put any installation disk in there. AND it just so happens my installation disk is snapped in half (mind you, i haven't looked at my installation disk in years so it could have happened ages ago) please help, i don't know what to do and am stressing out. I was thinking, should i just take it to a repair shop or try fixing it myself?
