Hi. My sister has an ol' iMac G3.. It has 10.4 installed on it..and..though it was fairly slow..it still worked fine. I had ram from my old iMac that I let her use..and I put it in and turned it on..it took forever to load..but I figured..mine always takes forever to load after I unplug it..so finally it started up..and everything worked fine. Then about a week later...she tried to turn it on..and it just gets stuck at the Apple screen with the spinning wheel.. Its not the ram..since I've put the old ram that was in it previously..and it still won't boot up.. Is it just showing its age? Or is it fixable? Thanks.
