well like the title says, my iBook was running just fine, and for some reason when i start it up yesterday it took like minute and a half to start up, when it usually starts in a bout less than a minute, and once its up i get the beach ball everytime i do something, is driving me crazy! my ibook, is a g3 800mhz, 640 ram, mac os 10.4.10, what could be wrong with it??
