Alienware m14x R2

Hello, I bought a Alienware m14x R2 in 2012 when I was in USA making my Exchange Program, last week my notebook stoped working and when I turn it on start´s to beep continuously, I contact Dell Brazil (my home country) and they said is a Mother-Board problem and need to me be replaced but they doesn't have here. What can I do to fix it??
