Help me please

[NBL khalifa]

i think 2 picture is enough to make you guys understand what kind of problem i had

back in the day my laptop got black screen after updating the nvidia driver , even on the bios startup , thus the only way i can get my laptop to work again is to reflashing bios , and it works

however after fixing the black screen problem , the gt 940mx on my laptop doesn't show up , i tried everything from downgrade the bios , uninstall all the driver with DDU , everything doesn't work , my laptop right now only detect the intel one not the nvidia , please help me when i tried to install the driver for nvidia it's said "couldn't find compatible hardware"

Both your image's/links don't work. Please make sure that you've posted the right links to the images. Upload them on Imgur if necessary.

Can you please pass on the make and model of your laptop? An SKU will help as well. It also reads out like you've performed a hardware level upgrade to get to the GT940MX, is that a right assumption?

I can't see your pictures (google hates me)have you completely uninstalled the nvidia driver & deleted them completely? So using only the Windows drivers. Another possibility is reformatting your laptop & reinstalling Windows. What OS are you using?

wait im going to fix that image

i fix it please have a look also like i said before , im using display driver uninstaller , lol no , i mean im updating the nvidia driver for the gt940mx (my laptop works well with 940mx in before im updating the geforce driver thus leading into blackscreen)
