If your picture (the one labeled JJJJJJ.PNG) is your MacBookPro - and a 2011 15-inch model, then you simply are another example of a failed logic board from that generation of MBPro.
Do a search for "radeongate", and you will see plenty of problems, a few fixes, but none that are permanent, unfortunately.
Apple did have a service program that would fix that issue at no charge, but it has been gone for a 3 years or so, and the repairs just used other repaired parts from the same models, which then had a number of those with multiple, identical "repairs" that did not last.
(Apple won't help now, because it is considered obsolete, no support now)
