code 43 problem on Nvidia graphics card

Hello, for several days the error code 43 has been displayed in my device manager next to Nvidia Quadro P620 graphic card. 
I tried to uninstall it, update the drivers and even reset my computer and nothing worked... However, when I analyze the components, no problem appears with the graphics card. By the way, yesterday, after a series of manipulations (too many for me to remember in detail!) the card started to work again. but when I turned my computer back on this morning the error had reappeared... if one of them comes in, you have the solution, it would be really cool... thank you in advance...
