Problems in Minecraft

Well yesterday I wanted to play minecraft so I got it and this little message popped up when I opened up the game

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.
