Problème Minecraft

Bonjour,
J'ai un problème.
Lorsque que j'essaye de joué à Minecraft un message sur fond bleu apparait :

___________________________

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.
