same problem
here's what i wrote in another post, any help???
about 2 months ago my mac "died". i'm using an iBook G4 800mhz 12". when i turned it on, the gray apple logo screen appeared and then it went to the blue screen, and where the "loading mac os x" box would normally appear, nothing happened. i tried at least 6 more times, and then i put it away and i was pretty convinced that it was broken. i got home, put in the panther disk that i had, which has worked in the past when i have a problem, and tried to boot off that disk so i could put a fresh install on. i thought i just had a bug on my hard disk so that would fix my problem. but then it didnt boot into that disk, just the blue screen again. i tried holding down alt, and then c, but still nothing happened. so i turned it off, waited a day, then booted normally, and my desktop came up, i thought it was fixed, but then it froze again after about a minute and a half since i pressed the on button. so i bought a firewire cable, transfered my important files that i wanted to keep onto a friends iBook computer, and then tried target disk mode to install a new copy of Panther. it worked, but then when i booted, it just went to the blue screen. after 2 months of messing around, i found out that the longer i waited in-between bootings, the longer i had before it froze. so i waited 2 weeks, and then i had enough time wipe the drive, install panther, restart, but then it froze. i waited another week, and i was able to go through setup, then it froze when i was done. 5 days later, i booted, my desktop opened, i opened safari, and it froze. i have also tried things like reseting the NVRAM, and the PMU, but neither made any visibe change. i even took the RAM out and put it back in...
any help??? i'm not in a hurry but it would be really great if i could fix it
thanks
