graphics card defect in the hp pavilion dv6000?

[EleanorWyatt]

Hello! on my pavilion dv6000, which is a little over 2 years old, the graphics card is probably broken (1x long and 2x short beeps as a bios error, screen stays black). then I looked for similar defective notebooks on ebay in order to possibly get a new mb cheap, but I was amazed when all potential candidates had exactly the same problem. now i wonder if this is possibly a general problem with the model. Does anyone know more? and whether it is worth retrofitting the mb in the case at all?
