a few hours ago my mac froze up so i reset it but when i turned it back on it was just gray with a folder icon with a question mark in the middle blinking. i then turned it off and left it alone for a few hours and when i went to turn it on again the screen is just gray with the apple icon and the loading icon under it, which is what always comes up when i first turn it on but it wont change, its been the same for like a half hour now.
any suggestions?
