Voilà j'ai un petit problème, j'arrive pas à lancer Minecraft sur mon PC fixe, je recois toujours ce message 
:
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.
