Hm, I've had this issue before. I believe I tried alot of the things you did, I believe I had to set my verison to a earlier one of 1.8 I stopped crashing after that, that was on my old laptop, my new one I haven't had as many problems.
I got this laptop about October 2014. I never really had problems with it except for the past week or so.
omg. I thought of another way to fix the problem (maybe) by downloading minecraft again and deleting my old one. I just tried it and it worked! Thanks everybody for the help!
