I have a very big problem

[TheCrafternaut]

Whenever I launch minecraft it runs fine but when i install forge this happens(i have fully updated video card drivers):

Crash report;

  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.
