Hey all, I figured I'd try in here and see if I could get some help before going to the 'Genius Bar' and being told I should cough up some loot. Couple of nights ago my computer got the spinny rainbow wheel when one of my programs froze. I waited about ten minutes to see if it would sort it out itself but it seemed like that wasn't about to happen. I did a manual shut down by holding the power button down. Waited a minute and restarted. It came back up fine but now if I started any application the wheel would come up again and each action would take about 5-10 minutes to complete. Did another manual shut down. Left it along for an hour and came back. This time I started in safe mode. Things were ok for about 15 minutes then the spinny wheel came back again. Shut down, waited an hour and then restarted. Now the grey start up screen comes on. Progress bar appears, goes forward about quarter inch and then gets stuck. This goes on for about 5 minutes and then the machine just shuts itself down. This is freaking the f out of me, and I don't understand what's wrong because I've never had any problems with it. The machine is past the one year warranty, and I don't have apple care (stupid I know). I'd try and reinstalling the OS but I just flew east and hadn't brought my disk with me. Any advice would be helpful. Thanks edit: Just wanted to add that it's a 15 inch macbook pro running snow leopard. Intel chip.
