please help!!!

the other day, my alarm went nuts, it kept ringing every 5 mins even when i already stopped snoozing it. it jus comes up without any alarm notice n i cant turn it off. i switched off my phone and when i turned it back on, my bold out of a sudden jus doesnt ring when i get calls. even when i receive a new message from blackberry messenger / sms. n now when i set up my alarm, it did not only NOT ring, it doesnt even show up at all (jus like when u put the alarm to off mode).

i checked the profile in normal active profile mode, so definitely not on quiet mode. help! i cant wake up without my alarm!!!
