Depends, i don't know your graphic driver provider but mine is NVIDIA. I suggest you to re-update minecraft (Get a fresh minecraft.jar) and try putting a pumpkin on your head again, if it's still not working then it's defiantly your GD. (I found a great solfware on Google, you this might help you finding your GD. Click Here to go to that page.)
Be sure to install it correctly, check your graphic drivers if there are any problem.
If you want a custom water/lava use MCPatcher, you will have to use this soon to StormCrafter HD. It will be released in the future.
