Почему Minecraft выдает ошибку

Когда Заходиш я нажимаю Login пишит Login failed нажимаю play offline Грузит и почти в конце идет черный экран 10 сек а потом выдает вот токую ошибку

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.
