I have an ibook G3 and yesterday the computer seems to have died. I turn it on and it sounds like it is trying to turn on, but no picture is coming up, and the hard drive is real loud. I can still press eject and the cd tray opens up. I have tried to see if it will work with the battery and also by running off of the power adapter. Sometimes colors flicker on the LCD screen. Does anybody know what the problem is or what i can do???? Thanks in advance
