GPU or Logic Board broken?

[ihaveagibsonsg]

Hello all. I have a Macbook Pro 2006 model A1211 specs here http://support.apple.com/kb/sp24

I believe either the GPU or logic board has failed on me. I know its almost a 10 year old computer but it still works well. Anyway it can be fixed and how much? I've built a couple desktop computers before, would this be manageable to replace the logic board on my own? Pictures attached below of error screens. The standard apple start screen appears to be OK but after it starts up I usually get these two screens and I'm unable to sign in.

Could be many factors: the GPU, loose display connector (from 10 years of bending and use), malfunctioning LCD.

Have you tried running an extended Apple Hardware Test?


And the ATi X1600 (now AMD) was notorious for malfunctioning.

I have ran zero tests....I'll look up on how to run an apple hardware test then reply with the results later.

I already did. It has a black and white checkered screen.

yeah what happens is over time the soldering balls under the GPU crack due to heating up and cooling down. what you need to do is reball the chip (BGA soldering) or you could simply heat the chip up with a heat gun to reflow the solder balls underneath so they create better contact again to fix this issue, I've never been unsuccessful with either method in the past
