Java constantly crashes minecraft

Put the summary of the bug you're having here

What I expected to happen was...:
In all modes whether single or multiplayer the game should run and did so up to about 2 weeks ago.

What actually happened was...:
Games freezes and I get a "Java TM Platform SE binary is not responding" I have re-installed Java, changed the video settings in the game following the forum steps but nothing works.

Steps to Reproduce:
1. Open Minecraft launcher - wait for the profile to load and click PLAY
2. When game menu opens - click multiplayer
3. Choose server - click join server
4. Game starts to build graphics and crashes
