Since last night, my Macbook Pro (2.33Ghz Intel Core 2 Duo, 15", Model A1211) graphics decided to become a complete disaster for me and remains inoperable. I am unsure what caused this problemmaking this problem difficult for me to resolve. Basically, my screen displays a bunch of graphic glitchy artifacts all over my display. I am unable to navigate through and eventually would freeze or turn off its screen. It even happens after a cold bootso, overheating is not playing a factor to this issue. What should I do? Try to boot from the OS disc? Could it be a hardware problem that I can repair? Any help is appreciated. Thanks! Here is a photo of what's happening.
