I am lost here.. Today my computer started acting weird. I was on a forum I frequent and trying to attach a file to my post and then the whole browser crashes. I tried again same thing, so I thought ok maybe something in Safari is quirky.. so I tried it in Firefox.... same deal. Sooo I then decided to restart my computer .. it took a long time to shut it down and kept telling me applications where preventing it from closing. I force quit my apps.. and then manually shut the computer down as it was not responsive. Then I restarted.. but it took several seconds before I heard that "chime" I got to the screen with the apple and the the mac version of an hour glass and it sat and sat... it did nothing.. just kept spinning that little circle. I shut it down and tried again.. then it freezes on that spinning little circle/hourglass thing. I am sooooo stumped I am hoping this is not serious.. I do not know how to load it in safe mode like windows has or anything.. I am a year into mac and have never had a problem like this at all! Is there a way to get the machine to start? The machine in question is a ibook 600 G3 it is currenty running Tiger and has the max ram configuration.
