Minecraft Forums

Hello everybody,
I apologise if what I am going to ask does not go on this section, but I am kinda new on this forum.
I installed Windows 8 to my sister and my cousin and I installed back Minecraft on their computers.
When I wanted to make it work, this message appeared and they could not fix it:

	  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.
