I have tried downloading and then installing this driver, many times.
http://www.nvidia.com/obje
It seems to install correctly but then when it restarts, Windows 7 no longer shows the monitor under display settings at all. However, it still lists the graphics card under Device Manager with no problems. In order to be able to dual-monitor again, i had to uninstall this new driver and then reinstall the video card drivers i have on CD when i bought the card.

See this Wikipedia article about Windows Aero:

In particular, this quotation under the "Requirements" section:
Microsoft has listed the following requirements for what they call a Vista Premium Ready PC. A PC that meets or exceeds these requirements will be able to use the new Aero technologies.[7]
Windows Vista Home Premium, Windows Vista Business, Windows Vista Ultimate, Windows Vista Enterprise (Aero is not available in Windows Vista Home Basic nor Windows 7 Starter editions)
a 1 GHz 32-bit (x86) or 64-bit (x64) processor
1 GB of system memory
a DirectX 9 compatible graphics processor with a Windows Display Driver Model (WDDM) driver, Pixel shader 2.0 in hardware, and a minimum of 128 MB of Video RAM
32 bits per pixel
40 GB hard drive with 15 GB free space
DVD-ROM Drive
audio output and Internet access (preferably broadband)
The minimum requirements for graphics cards from the major vendors include the Radeon 9500 from ATI Technologies, the GeForce FX series from NVIDIA, and even the Intel GMA 950. Though the last driver from NVIDIA to support the GeForce FX series on Vista was 96.85 [1],[8] Microsoft's WDDM drivers for NVIDIA graphics continue to support the GeForce FX series;[9] NVIDIA's current WDDM drivers support the GeForce 6 and later series. Though some of XGI Technology's Volari GPUs supported DirectX 9, no Microsoft WDDM drivers shipped with Vista and XGI has exited the graphics card business, so Volari cards apparently will not work with Windows Aero.
Note that though Microsoft has listed 128 MB of Video RAM as a requirement for "Premium Ready" PCs, it does not mean a 128 MB integrated graphics processor is required to run the Aero glass theme. A 64 MB integrated graphics processor, combined with at least 1 GB of system memory, will be able to run Aero at certain resolutions, however, the visual effects will be slower and less smooth.[10] However, a Vista-specific WDDM driver for any given graphics processor is also required to run the Aero glass theme;[11] these drivers may or may not be available. Users who believe their hardware meets Aero's minimum graphics requirements are encouraged to check their graphics processor manufacturer's website for a Vista-specific driver if they are unable to run the theme.
I'm afraid you will need a new graphics driver...
