A Minecraft miért adja ki azt h Bad video card drivers? Lent

Van egy minecraft launcherem, el is indult meg minden, de amikor betöltött ezt dobta ki:

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.
