Mac freeze at apple logo
Hi. I'm using mac osx lion. my mac freeze at apple logo and spining wheel. I try everything, command+s, command+p+r, option and shift. It doesn't change anything. I took out the batteries and hang it for 1 day, but its still stuck. The worse when I check into applecare website, they said command+v and see if there is some text written "library...." then I can restart and back to normal, but I can't find the text its not there. I don't want to lose all my data. I haven't backup anything yet. Someone please help!
