(1) Most important: If you are really afraid that your parents might hurt you, tell a police officer, clergyman, teacher, or some other trusted adult right away!
(2) If pennbank's good suggestion above doesn't work for you, I suggest you ask whoever sold you this new Mac to fix it or replace it immediately rather than trying to fix it yourself. Take quick action while your Mac is still new. Apple wants your new Mac to work right for you.
(3) BTW, I also answered at your other post on your problem: http://discussions.apple.com/message/20266789#20266789
