My log in screen is glitched?

[DJMdivine]

OK, finally after all of the graphics driver updating i'm done and I finally got it to work! Here's my problem now... while its loading up the SL logo is so far out glitched and are cut apart. When it finishes loading the bottom half of the SL logo is sitting there while the top half is the bottom half of the login screen... I cant scroll up or down and I cant login. What do you guys suggest I do?

Pictures of my problem.



What it looks like loading up.






After done loading and no I can scroll up or down it sits just like this.
