Minecraft ne marche pas, que faire ?

Salut! J'ai achetter Minecraft dernière version hier mais seulement quand je l'ouvre il me dit:


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.
