Why do I still have video glitches
Just wanting to get some possible answers of why i am still getting video glitches on my iMac 17"?
I recently had it professionally reballed for the GPU and after getting it back, i get video, but with lacking drivers. I put the regular drivers ("kexts") back and repair all permissions, i still get the horizontal black lines when it tries to get to the login window. This happens with the main machine and using an external monitor hooked up via mini DVI. Could it be a bad reball, or is there something else i am not seeing?
Is this a good question?
