Minecraft suddenly closes with no aparent reason. version 1.7.9

I was playing like any normal day. Expected Minecraft to run normal. With no bugs and crashes.

I was just playing on my new world. I had more than ten worlds, dont know how many I had. Then, suddenly, the game closes. No launcher. No Esc Home / Menu. Just closes. Also, my other worlds did not load. Also, when on Snapshots is on, it crashes and i cannot take screenshots. I currently have the launcher at : use latest version.

There seems to be no trigger at all.
