problema al iniciar minecraft

Hola, esto es lo que me pasa.
Cada vez que inicio me sale el error:

  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.
