My screen keeps flickering and I am having problems booting.


Hello, i have a 17 Inch MBP (non-unibody) model A1229.

First, when i boot, i get these two black bars on the edge of the screen, and the spinning wheel on the boot screen had frozen. Here's an image


I had followed the instructions on [|this page]

So i was able 2 boot the MBP. However then i had noticed that the screen was flickering incredibly fast (about 3 times per second) and the computer was unresponsive. I think it may be the graphics card, however i am not 100% sure. Please help D:
