I keep getting the following error when I attempt to launch minecraft:

#

1. A fatal error has been detected by the Java Runtime Environment:
   #
2. EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x27563e88, pid=3272, tid=3204
   #
3. JRE version: Java(TM) SE Runtime Environment (8.0_25-b18) (build 1.8.0_25-b18)
4. Java VM: Java HotSpot(TM) Client VM (25.25-b02 mixed mode windows-x86 )
5. Problematic frame:
6. C [ig4dev32.dll+0x3e88]
   #
7. Failed to write core dump. Minidumps are not enabled by default on client versions of Windows
   #

Any ideas?

Many thanks.
