1.10.1 And Any Other Version Crash

So i upgraded to 1.10, and was really excited! So i opened a new world and crashed. I don't wanna open my old worlds, in fear of them getting corrupted. I thought maybe it was fixed in 1.10.1 but it isn't. I have allocated 2 RAM instead of 1, and turned off VBOS. My VSYNC is on but i don't know if it has anything to do with that. It does ot on multiplayer, too. On 1.10.1 it takes about 30 secs to crash, but lags. And it crashed almost instantly on 1.10. Can someone help me? Thanks
