  1. Your team is Amazing!! After hours and hours of work I finally found your page. I was getting Code 43 with my 3070 Ti, and the Culprit was UPSilon (for my UPS). Uninstalling that and reinstalling Nvidia drives fixed everything!

  2. This helped. Thankfully already first step helped. When I turned on back notebook graphic card was working. It started to have an issue after driver update.
    Thank you. 🙂

  3. NO NO NO . ITS PROBLEM STILL HERE :((((((
    For 7 days there in not way which i didnt try but its still here 🙁 Please @NVIDIA save my mind ! ! !

  4. I tried everything on this list and the issue is still there. Everything is up to date, the Lucid MVP program was never on my computer in the first place, and I’ve uninstalled and reinstalled twice. My laptop doesn’t have an external battery to remove, and I’d rather not unscrew the back panel unless I absolutely have to, but since this is a new issue, it seems unlikely that the graphics card adapter somehow came loose. The Nvidia control panel appears to not actually be installed at all, no matter what I try, and the GeForce Experience control panel wont let me navigate to any other tab, and keeps prompting me to install the GeForce driver even after I’ve installed it. I’m completely at a loss.

  5. Thank you so much for this article!
    Tip 3 solved it for me (Got a Lenovo P52 with Quadro P1000 and it refused to work in device manager (just a yellow triangle with exclamation, stating error code 43)).

    Thanks again!

  6. Your comments say to uninstall 1) NVIDIA Physx System , 2) Nvidia Graphics Driver and 3) Nvidia Geforce Experience, but the figure says to do it in a different order. Which is correct?

  7. I have the same problems as Robert minus the black screen. I’ve tried everything. Used DDU to remove all display driver traces, reinstalled manually multiple different driver version going back months in hopes one of them would work. What was weird is that, when I checked device manager it showed my driver version but geforce experience didn’t seem to detect it, it would prompt me to download 441.66, I would, install it, it would tell me to restart, I would, then when I boot up again it would just prompt me again like I never did anything, super weird. I’ve tried everything on this list and the problem persists, I’ve even reinstalled my OS and completely reformatted my laptop and it’s STILL there. I’m completely out of ideas at this point.

  8. Just installed NVIDIA 441.66 Drive and lost the NVIDIA Control Panel and now have Code 43 errors on the Device Manager display. I tried all the above attempts and its still broken. After enabling at the end of Fix 3 I got a black screen. I was able to Remote Connect to the machine and saw a panel that said the device was enabled and then shut off with Code 43 again.

    441.55 is the latest and greatest from NVIDIA.
    I suspect that I don’t have the Control Panel entry since the Device Manager is throwing Code 43 problems?

    Any other suggestions?
