Okay so I have search here and google and it seems that I am the only one with this problem or really bad at finding what I need! (most likely the second one) My problem is that about two days ago my iBook G4 decided that it no longer wanted to work. Basically it wont move passed the start up screen (the apple logo with the pinwheel underneath) but the problem that I am having that no one else seems to have is that my computer will shut back down after about 20 seconds of the load screen?!? I replaced the Ram about 2 or 3 months ago, if that would have anything to do with it. Anyone have any ideas? Thanks in advance!
