Title basically says it all, but here's more detail. I was browsing the Internet on my MacBook pro 13 inch alumn 2.25 4 gig upgraded ram from crucial. And all the sudden i get the beach ball so I go to iTunes same thing I try and command quit them both doesn't work iCal works and so does aim. But after a few minutes safari and iTunes still beach ballin' so I power it off by holding in button. I go to turn it back onit powers up makes the usual chime and is on the grey screen with apple logo then I get the spinning gears or whatever. Ive searched google and all the stuff I found is outdated by years but I still followed what they suggested like holding in shift for safe mode did nothing. I also tried booting from the disc didn't work. I then tried resetig pram and it did nothing either. I also used the second cd to do the hardware test both ( short and quick) and no problems arose. I think that's all I did I can't remember it's late. Tomorrow I'm gonna call apple care and deal with it. Just thought I'd post to see if anyone else expierenced it and how they worked out. Most things i've read are HD failures
. Sorry for my spelling and such as I'm on my iPhoneright now. Thanks!
