    Hi Folks!

    I'm not new to the whole mac thing, been using them since G4... but what I'm about to BEG for help is out of my reach...
    I recently bought a second hand i7 MBP 2010, and it seems to be playing funny with me. i've done few things to see if any provident is achieved with no success.. SMC, Nvram, and sorts at boot..
    For some reason, sometimes it displays the wrong date and time at startup (my guess, pram battery) but thats minor. now the interesting is when out of the blue i get the panic, and I'd like to share the log.. I'm not really sure what it says¿?¿?¿ so PLEASE HELP!!!

    Don't want to worry you but this sounds like a hardware failure (at the software end), as I can tell from the kexts that are crashing.
    The only thing I can recommend is completely wiping the drive and installing OS X from scratch.

    Another thing you can try is stress testing the hardware with a benchmark utility such as NovaBench to see if it hangs again.

    EDIT: This is the culprit GPUPanic.cpp:127 - the GPU is failing.

    Yep looks like a GPU failure, there was an apple repair scheme on this model for that reason, although that is long over now.

    oh what a c**p... that means $$$ in my language.. the thing is that I thought so too.. but yesterday I stressed the GPU to a limit where the computer wouldn't even react, and nothing happened... today while doing simple tasks it panicked.. I'm gonna try the benchmark and see if it happens.. do you know of a video oriented benchmark to stress the gpu? many thanks for the reply!

    It may be the solder going and it goes when it's moved or cools down so stressing the GPU may not show what you want apart from finally causing it to fail completely in this case the GPU is fine and it can be reballed but only a technician could tell you wether that's the case or not.

    It's the risk you take buying second hand out of warranty computer I'm afraid.

    Like Samuel said, when it gets hot and the solder is going it breaks the connection to the motherboard causing the computer to crash. I'd suggest taking it to a repair centre and get them to re-mount the GPU/CPU with thermal paste and re-solder to the board.

    I had this experience with an old Toshiba laptop that would just switch off intermittently and it was said to me that the board had a hairline crack, which meant as it heated up the board would lose connection, and therefore, power.

    Probably not the answer you were hoping for, but I WOULD suggest a complete OS re-install from scratch to see if it is a corrupted kext.

    I have done the benchmark test and with the openGL test the Laptop resets straight away.. so I'm done.. :( gpu issue all the way I'm afraid.

    If I were you I'd send it back to the seller and ask for a refund saying that he has sold you faulty hardware. Don't want to let you down but it's probably the reason why he sold it and "maybe" didn't tell you of the problem.

    Its a fresh Yosemite installation on a SSD... I could try, but the system hasn't even had time to mess with permissions.. You guys think it would help??

    EDIT: Yeah, I've tried with the seller, but he isn't even from my area.. and tbh, i don't think he'll just refund me the money.. I live in Spain, people here don't give a damn if you don't like what you buy.. money is making people mad over here...

    Anyway, thank you very much for the advise! I guess I'll have to do something, cause this is a pain and can't keep on switching to the integrated graphics card.. it sucks!

    Personally I think it's a long shot but it's worth a try.

    An apple technician may be your only answer at this point. If it is just a reball and thermal paste application it will be a few hundred euros but you may be able to get another that age for that sort of money.

    I would say if you are going second hand again get a 13 inch they don't have a dGPU and are far more likely to last.

    As tough as it is for me to say it, the integrated Intel HD 4000 GPU is far more reliable than the dedicated GPU, as it is part of the CPU and shares the same memory bandwidth, along with the same cooling, meaning the only way it could fail is if the Intel Core i5 (or i7) itself fails, which is EXTREMELY unlikely.
