Error Code 43 - Nvidia Geforce GTX 1650

[KachitoJr28]

After updating my OS to Windows 11 and upadating the BIOS version as well, my Nvidia Geforce GTX 1650 started showing error code 43. I have tried all driver installations all to no avail and I am unable to downgrade my BIOS version. What can I do now to get my graphics card to work

Since Error Code 43 persisted after your Windows 11 and BIOS updates, and driver installations failed, the most critical step is a complete driver reset using **Display Driver Uninstaller (DDU)** run in **Safe Mode** to ensure all conflicting driver traces are removed before reinstalling the latest NVIDIA driver. If that fails, check your **BIOS/UEFI settings** to confirm the primary display output is set to **PCIe/Dedicated Graphics** over Integrated Graphics, and try disabling Windows **Fast Startup** to force a full hardware re-initialization. If the issue remains, the conflict is likely a deep, unpatchable incompatibility between your new BIOS version and Windows 11, requiring you to contact your computer manufacturer for a specific hotfix.
