My nvidia 8600M GT in my Macbook pro just died yesterday. My warranty ended 8 day ago. It started with random gliches the same lots of you allready wrote about, then suddenly when I was using safari my macbook died. I still can turn it on from time to time but 9 out of 10 it hangs on completely distorted gray apple. Way the go nvidia. I wonder if apple is going to do anything about it?
