Blue Screen of Death in an Alienware X51

I bought an Alienware X51 a little over 1 year ago. About a week ago, monitor started blinking and I was receiving some messages like "Display driver stopped responding and has recovered", but now it is started showing Blue Screens of Death. Several in a row, just a little after booting. Now things got even worse and the computer doesn't even boot, beeping sometimes twice, sometimes just once.

I don't live in US, so I can't call support by phone. And I can't find a way to send an e-mail message to technical support.

Does anybody know what is going on and what i can do?

Thanks
