Minecraft ne marche pas aidez moi svp

Bonjour, CCM
aujourdhui jai eu minecraft mais quand je le demarre il maffiche ca

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.
