Miért nem megy a minecraft?

újraraktam a gépet ráraktam a minecraftot és amikor elindítom (legernerálta a .minecraftot meg ilyesmit)és ezt írja: 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.
