Mon Minecraft ne Marche pas...

Bonjour, il y a peu de temps que j'ai acheté Minecraft et quand je met Login, sa ne marche pas et sa écrit ça:
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.
