MacBook Pro blue horizontal lines error

Hey everyone
I'm having troubles with my macbook pro i bought about 2 years ago.
I've uploaded a video on youtube thats shows how it's behaving...
YouTube - MacBook Pro blue horizontal lines
When I recorded the video I could wait a while and then start it up again, now I can't even start it.. The blue lines is the first thing that pops up.

It's a 15 inch, 2.4 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM, Version 10.5.6

Hope someone can help...

There is a known defect with the NVIDIA GeForce 8600m chip that powers the graphics subsystem of your MacBook Pro. It can manifest itself in a variety of different ways and this is one of them.

Apple has extended the warranty to cover this specific problem for an additional 2 years beyond your original warranty. I would either set up a Genius Bar appointment at your local Apple Store or contact AppleCare directly.

Okay... That sounds fair enough.
I think I'm gonna head down to my local store right now.
Thanks...
