Very strange... would you mind informing me of what version of java you are running on what OS- and, like always, if java isn't on version 7- update if you can.
Windows 7
Java 7 version number stuff (just updated it today)
Java has 6Gigabyte Ram allocated
I'm running Minecraft with 6GB also
Even in another Modpack I'm building at the moment myself everytime I try to access Recepies through NEI or CraftGuide it crashes. Well... not always it starts getting buggy after 2mins of gameplay.
I'm just updating my Graphics card drivers but I guess it won't do anything
