Macbook Pro (Mid 2010) kernel panic issues
Hi, my Macbook Pro (mid 2010) OSX 10.8.4 with SSD started displaying weird screen artefacts last night. As a precaution I shut the machine down. Upon restart, it started having kernel panics, and would then restart automatically after displaying a message stating my machine needs to restart. Eventually the login screen appeared and I logged on. As soon as I logged on, moved the mouse, the screen started scrambling again, and the attached external monitor was fine. I also noticed it when I was downloading something from Safari (the download window seemed to be distorted and scrambled).
I tried starting up in Safe mode and the machine got kernel panics. I tried doing an Internet OS install, and it came up with an error message something like: -1020 (12) error. I tried resetting PRAM, that wouldn't work. Tried doing an FSCK. That worked, and after the message "system appears to be modified" I ran it again until "system appears to be OK" appeared. Restarted, and the same thing happened.
I then opened the machine up, and replaced my SSD with the original HDD that came with the machine, to see if it was an OSX system failure, but the fault was still there. Eventually the machine won't boot properly, and sometimes chimes around 5, 6 or even more times.
Not sure what to do now, as I'm not sure if it could be a logic board issue, RAM issue or video card issue.
Also, would this specific logicboard be one of the recalled ones, or would this be a repair at my own expense job? Worth a try in any case.
Any help would be greatly appreciated.
PS, I'm pretty technically minded and know my way around Macs, so please do send me any helpfull suggestions.
Thank you in advance,
Adrian
