malfunction on a video chip on logic board
I need you professional opinion...
My MacBook Pro 15" i7 early 2011 system was diagnosed with a bad video chip on logic board (diagnose from an Apple dealer).
My laptop is 28 mouths old. Apple doesn't care about it, because is out of warranty and I didn't get AppleCare. My MacBook Pro has two graphic cards, when I open a photo in lightroom or photoshop, it freeze the screen… I need to reset a lot of times, to restart with other graphic card. My opinion, the new MAC OSX Lion 10.8.4 has an incompatibility with the ATI graphic card… but they disagree with me. I can’t start my laptop with the original DVD’s (MAC OSX snow leopard 10.6). Can you give me some advice or help?
Is this a good question?
