Hi recently my minecraft has started crashing on world load up. The launcher log states that it is in the java virtual machine. The error reported is EXEPTION_ACCESS_VIOLATION. All versions under 1.7.2 work. I have been doing some research and it is due to an OpenGL something in my graphics card. However I have been able to run all versions including the 1.8 snapshots, until recently. The problematic frame is ig4icd64.dll.

All help would be greatly appreciated.
