Miért csinálja ezt a Minecraft?

Ezt írja ki, és nem tudom mit jelent és hogy oldhatnám meg a problámát?:

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.
