Ok guys, Yesterday my Macbook started acting funny and several programs started freezing. I went into the finder and force quit the browser and a few programs like entourage and mail. I was still having problems so I shut the computer down to reboot. When I turned it back on, the little thing just kept spinning for about 5-10 minutes. I turned it off again, removed the battery, cordless mouse, power cord for a minute and reconnected everything except the cordless mouse. Now then I book up the computer, I get this flashing folder in the middle of the screen with a question mark in the middle. I have no idea what this means and can't seem to find anything on the mac site making reference to it. My apple care JUST EXPIRED and I am trying to troubleshoot it before taking it into the Mac Store to pay a fortune to get it to work again. HELP PLEASE.
