My minecraft won't start

When I press play it starts loading minecraft but after a while it just says: "no response" and this happens in the new versions. Sometimes i get in but, if i create a new world it freezes there and i have to restart my pc again. And if I go to multiplayer it loads in and freezes. Also when i close it it says: "An unexpected issue occured and the game has crashed. We're sorry for the inconvenience." And i cant view the crash report.
