Since doing this i can no longer see the 2nd graphics card, can anyone help please?

    Previously i had the following set up:

    Windows Vista 64 PC with 3 monitors on 2 graphics cards (GeForce 8200 & GeForce 9500GT)
    Motherboard- ASRock K10N78-1394
    Chipset- GeForce 8200
    Bios- American Megatrends P1.20
    CPU- AMD Phenom II X4 955

    My PC has been sluggish since i bought it and crashes quite often, which i put down to Vista so I decided to upgrade to Windows 7 but discovered that the CPU was only running at 800MHz rather than the advertised 3GHz. I was told this is a bios issue and to update the bios to AMI P1.60

    After doing so i can no longer use the 3rd screen and i cannot see the 2nd graphics card (GeForce 8200)

    The system shows that the motherboard chipset is now nForce 720a and the graphics card as GeForce 9500GT (no sign of the 8200)

    The CPU is now faster though!

    Can anyone advise how to get the 2nd graphics card (3rd screen) back?

    Many thanks

    did you try re-installing the cards and drivers? for sli i think you add one card install drivers add second reboot add third ect

    for cpu speed 800mhz could be the power saving modes? if under load the cpu speed should shoot up to 3ghz,test by using high performance profile in win7 power saving options,use balanced if you want cpu to downclock when idle

    With a single video card already installed, you probably need to install the second card, boot into windows and install the exact same driver software a second time. You'll know if the driver installation is OK if the windows device manager shows both video cards and there are no yellow warning/error icons for both video cards. You might need to manually enable SLI using the Nvidia software.

    Another way that might work is to remove your current Nvidia software/driver, boot into SAFE mode to run Driver Sweeper to fully purge your system of Nvidia graphics drivers ONLY. Then you will shut down your system, remove the psu power plug and install your second card. When you reboot your system install the latest Nvidia drivers for your operating system and graphics cards. This single software/driver install worked for my SLI system. I haven't checked out your video card, do they both belong to the same gpu family. Do they need an SLI bridge?

    http://www.google.com/url?sa=t&sourc...Ea5C4UMt-CVEzw Introducing Hybrid SLI Technology [PDF] might have some useful information.

    It sounds like your motherboard bios is not optimized for best performance.

    Nvidia has some excellent FAQs and information at Support - GeForce where you can download the latest drivers, demos, etc.
