I'm not doing much at all in my game (minecraft) and then suddenly it crashes, this has happened more then once and it hasn't happened just for today. I keep getting this crash since I made this survival world.

Part of it says

"Error has been detected by the Java runtime environment:
EXCEPTION ACCESS VIOLATION "

Then another part says:

"Failed to write core dump mini dumps are not enabled by default client versions of Windows"

Can you help?
