Problem with my display in macbook pro 17inch (earlie 2008)

Hi to all,

I am an owner of a mac book pro 17inch.

I bought it at 2008 and now i have all of the right side of the display having blinking stripes.

my system use Nvidia 8600GT.

Is there a graphic card issue or what?

Please i am a professional and i need a solution in order to work.
