Twin Frozr lll

How do I upgrade the video bios of a graphics card. Also I just bought a new card and I have white lines across the screen at boot up. It gets worse and the screen resolution is all wrong....
What are these white lines? Is it fixable?
Its the new card causing this problem and it has been isolated to just this card but I wonder if there is something I can do, or if its just a dead card....
