AMIBIOS

I just got this HP mini 1000 (p/n: fz978ua#aba)
I didn't have any problemsy first couple days, but now it is popping up American Megatrends on startup. The bottom says: "CMOS Setting Wrong"
if I press "F1 to Run SETUP" it takes me to a black screen that says "Enter CURRENT Password" After three wrong attempts, it says "Fatal Error... System Halted. [edited Serial Number by Moderator]" Help! why is it doing this, what do I do about it?
