Minecraft keeps Crashing.

I try to play ANY minecraft version, but when i join a server/world, my game crashes. Many "fixes" don't work for me and i really want to play this amazing game. I have the latest launcher and the latest java version - 1.8.0 121. I really want to see the blocks again and carry on making videos about it . When my game crashes, i have to go into .minecraft to find the logs so i'll find the latest one. The latest one has a few lines and then stops!
