The game would crash completely at random, whether your playing on a server to breaking a dandelion.  I can not find a way replicate it but it happens (very much at random) when i play my single player world.

But i will state all the things that happen prior(in order):

-Music stops

-Games starts moving at 1 fps and is extremely choppy 

-Everything freezes 

-Page no longer responds

-crashes

i'm really sorry if this is a bad report but it has been happening to me about 4 times an hour at this point and I really can't take it.
