Sony VAIO Vpcea23en — hard disk & speaker compliant

I am owning VPCEA23EN laptop and i am facing the hard disk problem. It was working fine. All of a sudden the blue screen of death came and after that its not booting at all. I have all my data lost. I m too frustated. Very worst laptop ever had. Who will bare for my loss?I had used Lenovo, HP and found it much better. I got that on June 2010. I have Sony TV, Home theater. Even my car stereo is Sony. I had lot of trust on Sony. But now
I am fooled easily by Sony Corporation.The lifetime of the laptop is just 2 years, and for that i had to pay 42k. It makes me to think about all the other investments in Sony and my future plans to buy Sony Products.
