Strange resolution problem after updating Nvidia display drivers

Due to some weird problems I was experiencing with my graphics cards, I was forced to update my drivers. Original issues aside, after the installation process (yes, beforehand I booted into safe mode and ran a driver cleaner and everything), I noticed that my screen resolution was set at 1680x1050 instead of my preferred 1440x900. I also noticed that 1440x900 was missing from Display Properties altogether!

I went into the Nvidia Control Panel > Manage 3D Settings and changed the Multi-display/Mixed-GPU acceleration feature from "Multiple display performance mode" to "Single display performance mode", which restored the 1440x900 resolution in the options. However, switching to that yields this result:

The screen cuts off on the right side, leaving just black. There is a gray bar which cuts across the bottom of the screen, below which there seems to be a "copy" of the topmost part of the desktop. Also, down the middle of the screen there's this weird black line thing with little tick marks that seem to rapidly scroll up and down across it.

Just to make sure this driver (Forceware 185.85) wasn't faulty or something, I rolled back to several previous drivers and each has the same problem, including the one I originally had installed (179.48)! I should also mention that using "Manage custom resolutions" in the Nvidia CP has the same effect. Attempting to take a screenshot using the Print Screen key only saves the upperleft most "section" of the display, thus my having to photograph my screen. Are my cards just plain broken or is this something that can be remedied? Any ideas would be greatly appreciated.

Sorry can't see your picture at work.
Sounds like one or both video cards defective.
Not sure if you can replace them in a notebook.
