NVIDIA has said in their official statement that this software is causing discrepancies which is the reason behind many problems, along with Code 43. The Lucid VIRTU MVP software is used to switch between your onboard graphics card and the discrete one, which is an important use.

Many thanks,
The driver disable and enable worked for me, no need to restart in my case
Omar says
I tried everything, but still failed. NVIDIA often cause problem as well as on my mac the other day.
Katherine says
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.
Richard says
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!

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?
Pat says
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.
Robert Schreiber says
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?
