Screen Position Messed up After Driver update

I have a 7900GS and I downloaded the new driver. I uninstalled my old driver. Restarted. Installed the new driver. But when I put it to the native resolution of the monitor (1440 x 900) the screen is cut off at the right. Like, the clock and stuff is gone. If I put my mouse at the right edge of the screen, then it like auto scrolls and I can see the clock but this is gay, shouldn't it just fit?? I mean it fit before with the same resolution. How do I fix it?
