Computer froze and we shut it off . . . but when we tried to restart, all we got was a white screen with the Apple logo in the center . . . and it never made it past that. Tried three times. We have the startup disk . . . but really don't want to lose everything on the computer if we can help it. Help . . . please!!! "We," by the way, is mom on one side of the country - me - asking for help on behalf of son on the other side of the country at school. Thank you!!! Oh, almost forgot - it's a 2009, I believe, probably running snow leopard.
