Description: Upgraded to Windows 10 and the nVidia drivers either failed to load (screen resolution is not right) or Windows Update installed Microsoft drivers and will not allow for the nVidia Software to replace those Microsoft drivers.
Common customer description: I upgraded to Windows 10 and now my display is wrong.
Probing questions: Really no probing questions as the problem is evident and straight forward.
Steps to isolate: Check Device Manager and verify what drivers are being used. Either Windows Video Adapter (a basic and generic driver because Windows Update tried and failed to install Microsoft version of nVidia drivers) or an nVidia driver that reports an error 43.
Steps to resolve: The steps can be rather lengthy but if performed in this order you have a very good chance at resolving the issue until the next Microsoft driver update for nVidia.
1: Go here https://support.microsoft.com/en-us/kb/3073930 using Edge (aka Internet Explorer) and download/run the file. Can only be run using Edge (aka Internet Explorer)
2: Click on Next.
3: It will scan for the updates
4: Select Hide Updates
5: Check mark the drivers you want hidden and click Next (hiding the update means Windows will not try and install that particular update)
6: You will see a screen like this until it is done
7: Once it is finished you can just click close and move on to the next step.
8: Now that the update is hidden it is time to uninstall anything nVidia related. Go into Control Panel
Use the Programs and Features tool to uninstall all nVidia softwares. Once those are removed, reboot.
9: Download Version: 353.62 WHQL Release Date: 2015.7.29 Operating System: Windows 10 32-bit or 64-bit drivers (depending on which you have on your computer) and run as Administrator and the custom (advanced) install.
10. When the drivers are finished installing you may NOT be prompted to reboot the computer. Your screen may or may not have the correct resolution. Your screen might have even gone black even though the monitor power light still shows like the screen is active and not asleep. You still need to reboot. If the screen goes black, wait 20 minutes and power off the computer. Then after 15 seconds power it back on. Do NOT use a reset button. After the power cycle the drivers should now be updated and to the correct resolution.
Additional considerations: If you display stay black even after the power cycle, just power it off and back on until you can get into recovery mode. This will allow you to revert back to the generic adapter. At this point you need to figure out if you want to keep trying to fix the issue or downgrade back to Windows 7, 8, or 8.1 (whatever you started with).
