I'll try to give all the details as succinctly as possible. I have an early 2011 15" macbook pro. It had started to randomly shut down/restart (which I found out was a kernel panic). I decided to give it a full overhaul: -installed new sandisk ssd (replaced the original spinning drive which I repurposed as a second drive to replace the super drive) -installed 16gb of ram -fresh install of of OS X El Capitan as soon as El Capitan was finishing up installing a kernel panic happened. So now I'm assuming it's not a software issue and probably not an issue with the hard drive or ram. As I'm typing (obvi on a different computer) I'm watching the little spinning icon. It doesn't look like it's going to fully boot up. Not really sure where to go from here other than bringing it to a specialist. Was hoping someone here would have suggestions on something else to try. Thanks in advance.
