How do I update my video card drivers?

I opened up minecraft and this message appeared in the middle of my screen

' 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.
