After installing it at night (with instructions from iFixit) the next morning the computer will not turn on. A visit to the Apple store made it clear that the problem is with the logic board and they said it's not worth fixing. So my question is if this could be caused by installing a false pci card BCM94321MC. And if there is a cheap fix for this. Thanks in advance for any helpful answers.
