bonjour à tous, hier soir j'ai formater mon pc, donc remise à zéro, tout se passe bien, ce matin je réinstalle minecraft, je rentre mon identifiant, mdp, login, ecran noir... suivi d'un 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.
