For at least 9 months from now I have been getting random crashes to where it just reverts back to the launcher Game Output. After every crash it creates it leaves a file in my .minecraft folder called "hs_err_pid[random 4 digit number].log" inside everyone it says something similar tohttp://pastebin.com/T6DG5CFkLike I said before, this has been happening for over a year now and I'm finally so annoyed with it that I want it fixed. The only mod I have on is Optifine and I've already tried uninstalling it but this still happens. I have also tried looking up guides on how to fix it but they're all either trolls or severely outdated.In the Game Output screen it says ## A fatal error has been detected by the Java Runtime Environment:## EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00007ffbf9a334c6, pid=4732, tid=5100## JRE version: 7.0_21-b11# Java VM: Java HotSpot(TM) 64-Bit Server VM (23.21-b01 mixed mode windows-amd64 compressed oops)# Problematic frame:# C [ig4icd64.dll+0x434c6] DllMain+0x1a446## Failed to write core dump.
