Windows 10: Fix error 43 on nvidia graphic cards

There are lots of posts on the internet regarding to this issue. mostly addressing you to uninstall the graphic driver and reinstall it. sometimes it will work most of the times it wont.
some people suggest that error 43 means that the graphic card is dead or it is showing the symptoms that it will die soon. but as you still see your OS on the screen it means that the graphic card is still working.
In my case i have 2 Geforce 765m on my laptop. one day when i turn my laptop on, i saw that the SLI were not working because of the cards responded with some kind of hardware failure to windows and windows dealt with it by showing me the nasty error 43. I tried many suggestions including reinstalling the driver. changing graphic card slot and ... none of them worked.
what i did was that i copy the video card bios from the card that works fine and flash it on the troubled one using Nvflash.
did a restart and it works.
I believe if you see error 43 on your graphic card and get no result by trying the usual reinstall the driver solution, do not quit on your graphic card. find a card the same as yours. copy the bios from it and flash it on your card.
first make a back up rom from your current bios.

if you have a working video card right now be sure to make a copy of your V-bios right now. you might need it in future.

Windows 10 graphics card error 43

Ever since i have upgraded to windows 10, I have been getting error 43 , display device reported error . And then the display defaults to my CPU graphics. I have an EVGA NVIDIa GeForce GTX 670, I have emailed EVGA, with no success. I emailed Nvidia, they
suggested I uninstall my graphics drivers, reseat the graphics card, then when windows powers up ans sees the card, let it install its generic driver to see if I still get error 43. Well windows never saw the graphics card as a new card, or even tried to
install drivers, it just went straight to error 43.

So I can see this is strictly a Windows 10 problem. And I can not find anyway to email or contact Microsoft to get any answers. Its getting pretty old. I dont know is creating the media and doing a clean install will even help this problem out, I pretty
much doubt it.

 

Windows 10 / Nvidia 1030 - Code 43


After a Windows (Win 10 Home) update yesterday afternoon my son's PC reported the problem shown in the image below.




The result of this means he cannot play the very popular "Fortnite" game which reports this error.





Assuming the problem is caused by either the Windows Update or a driver update have done the following;

• Re-installed the latest Nvidia Driver. This didn't fix the problem.
• Installed the previous set of Nvida Drivers. This didn't fix the problem.
• Via the Control Panel / Device Manager I disabled and enabled the device. This didn't fix the problem.
• Via the Control Panel / Device Manager I used the "update driver" feature. This didn't fix the problem.
• I did a system restore to the day before. This did not complete with Windows reporting the Anti Virus software may have prevented the process. Default Windows Defender is the AV.
• I disabled the AV and tried system restore again. This didn't fix the problem.

In all other areas the system is functioning fine although my son said he had low FPS on Rainbow Six Siege which he tried to play when Fortnite wouldn't launch.

The PC is just over a week old so I am doubtful of any hardware issues with no other symptoms or errors showing.

So...any ideas or suggestions for next steps please?
