Macbook pro frozen at start up?
here's how this started:
itunes froze, so i tried to forcequit. nothing happened--the whole thing was frozen. so i manually pressed the power key and held it down. let it sit for a while. then i turned it back on. it's stuck at the opening apple logo with the white background now for like 20 min. i tried the same thing again--with the same results (i.e. holding power button down.). then i came back and found a bar partially loaded at the bottom of the screen with teh apple logo, and it's just frozen there.
this time while i let it sit to load, it shut off by itself...
please help!!
