Don't use fastcraft or optifine if you are and turn off anti aliasing and advanced open GL. That'll probably solve the issue as well as updating your graphics drivers
I disabled fastcraft have advanced opengl and anti aliasing off. have the latest graphic drivers and it still crashes. then if I don't delete the world before I open another one that glitch with the lighting happenhappens making me need to delete the world and restart minecraft to get it to go away.
