Does not boot but fans run
I have made a huge mistake!!!! I tried plugging in a internal hard drive into my Intel Mac. Unfortunately, it was the wrong connection. When I plugged it in my screen turned off. I turned off my computer and tried starting it. When I do I see could hear the fans turn on and it feels like my Mac is running but nothing shows on my screen. I looked over my mouse and there is no indication that it's getting power also. Did I really screw things up?!?!??!
Is this a good question?
