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.

Did you check your kernel extensions?

You can go to About This Mac/System/Report/Software/Extensions

or

In a terminal window:

kextstat -l | grep -v com.apple

should show you all of the non-apple extensions. I was having some problems even after reinstalls but found some old extensions that were still being loaded. Went away after I removed them.

You can also check:

/Library/Extensions
/System/Library/Extensions I think all of these are apple so I wouldn't touch.


Be sure you know what you are doing if you remove them - could be very dangerous to your system!

Depends upon how you define "fresh". If you completely wiped your hard disk, did the install, then restored your user data without installing any applications then yes, this would not apply.

My "fresh" (sorry, maybe bad wording) was to reinstall El Capitan from my recovery disk since it would take me a week to reinstall all of my software.

The checks above take just a minute or so so I'd check anyway in case something else installed itself as an extension.

Thanks CoastalOR. I'll have them check it out. I tried wiping the ssd again and reinstalling the os, this time back down to mavericks. Same thing happens when I try to shut down - kernel panic. here's the problem details:

this is way beyond my knowledge. would the above indicate whether I am experiencing what CoastalOR mentioned?

The panic and the backtrace would strongly implicate the GPU so I would agree with CoastalOR. Your time would be better spent getting that looked at first before trying other things.

The kernel panic does show the GPU was involved. Definitely make an appointment to have Apple test it.
