Minercraft dando erro ao abrir - Bad video card drivers!

Pessoal, quando eu tento abrir o jogo Minercraft está dando o seguinte erro:

Bad video card drivers!
-----------------------

Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.
