This indicates either a physical hardware fault with the card, a dirty AGP/PCIe slot, or that the graphics card model is too new for version 5.163 to recognize.
This is a common procedure, but it must be done correctly. Here is a generalized method:

: If you have more than one NVIDIA GPU (e.g., you are using a secondary card to flash a bricked primary card), you must target the correct one using the --index flag. For example, to flash the second GPU (index 1), you would use: nvflash --index=1 -4 -5 -6 newbios.rom .

Flashes the designated BIOS file to the EEPROM (standard flash). nvflash -v
The answer lies in the evolution of NVIDIA's GPU architectures and the security measures implemented alongside them. Prior to version 5.163, many NVFlash releases lacked proper support for the emerging (Unified Extensible Firmware Interface) standard, which was becoming the norm on modern motherboards. The situation became more complex with the release of NVIDIA's Maxwell architecture , which includes the GeForce 900 series and GTX 750/750 Ti.
Obtain the files (typically nvflash.exe and cwsdpmi.exe are required).
Obtain an old, standard PCI (non-AGP, non-PCIe) graphics card. This indicates either a physical hardware fault with
: Create a bootable MS-DOS or FreeDOS environment on a USB stick, often using tools like Command Execution : Common commands used within the DOS prompt include: nvflash --list : Identifies the installed GPU index. nvflash -b backup.rom : Saves the existing VBIOS for safety. nvflash -4 -5 -6 newbios.rom
(If you are intentionally cross-flashing or overriding hardware IDs, use nvflash -4 -5 -6 new.rom instead).
Change the boot priority to make the USB drive the primary boot device. Save changes and exit.
