    I have just had my logic board replaced on my macbook pro 13" (early 2011) after spill damage destroyed the last one. Now it seems i have no operating system on it. When i try to install snow leopard from the disk i got with the macbook it shuts down before the installation is complete. I have wiped my hard drive and performed repairs but still no joy. Do i need to purchase a retail copy of snow leopard or is there something else wrong? Any help would be greatly appreciated. Thanks.

    Was it replaced by Apple or did you do it yourself.
    If it was done by Apple it should have an OS on it.

    Try holding down the Option key, what does it show, are there options to boot of a disk, if so select it and look how it goes.

    Weird that it restart before it finishes.
    If it's done by Apple contact them, they didn't do a good job.
    You can also try to go into reccovery mode, hold Command-R at startup.

    It wasn't done by apple I bought the logic board myself and had a repair shop in my local town install it. They said i just need to install the os from the disk i got with the macbook but i've tried this multiple times with the same results. I'm currently running it in internet recovery mode. I have read in other forums that i might need a retail copy of snow leopard because the disk i have is machine specific and it won't be compatible with the new board.

    wait. Back up. When you got a new logic board, did you get the same model (early 2011) or a newer logic board? Because the early11 is the last to officially support snow leopard. otherwise, if you replaced a broken logic board with the same model's logic board, your grey disks should work.

    What I also do not get, is that if your logic board was damaged and replaced, why would your hard drive not be in order (system, files and all)?

    The logic board i bought is from the same model so as you said it should work with my grey disc but the macbook just gets a grey screen and shuts off just before the end of the installation process. I've tried multiple times and got the same result each time. As for the hard drive i only had the macbook about a month before someone spilled a drink on it and i didn't have any important data on it so i erased the hard drive in an attempt to perform a clean reinstall of os x but still got the same results in the end. My disc has a small scratch on it, do you think that would affect the installation?

    The fact that you're using internet recovery tells me you have 10.7(or later) on the machine, AFAIK, apart from completely formatting the HD to remove any trace of Lion(or later) on it, you won't be able to install SL with Lion(or later) already on there.

    Ok I managed to get snow leopard installed after making a copy from my scratched disc to my external HD and booting from that but now my macbook is running very slow and my trackpad has no swipe functions. According to my activity monitor kernal_task is using %300+ of the cpu. Anybody know how to fix this?

    Sounds like your new logic board is defective or the damaged it or some other components installing the logic board . Doesn't sound good

    Call them up now it sounds like you are experiencing hardware issues !
