Have new 3847 Inspiron 6847 w/Windows 10 and trying to install GeForce 9400GT graphics card. Cannot get system to recognize the card. Security Boot is off. Is there something that needs to be done with UEFI as well?
LEGACY CSM and Option Roms must be ON with secure boot off and then the LEGACY driver must be used. The latest and Greatest NVIDIA Driver DOES NOT WORK WITH Geforce 7/8/9 series and older cards because NVIDIA Dropped support for them in April 2016.
