Minecraft Bad Video Card drivers

Bonjour,

J'ai un ami qui joue à Minecraft et voici son message d'erreur :

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.
