If you have updated to Windows 10 and have an nVidia Graphics Card (in my case, two 970s) and are having issues with installing driver software follow these steps.
Before we begin, download the latest drivers from nVidia here, extract them somewhere you can locate easily, but do not install yet!
Control Panel > System and Security > System > Advanced system settings (on the left hand panel)
Once there under the Hardware tab select
Device Installation Settingsand make them match the image below.
Control Panel > Hardware and Sound > Device Managerand uninstall and drivers of devices with a "!" icon, it will likely say "Display" as the device.
On the Device Manager select
Action > Scan for hardware changes, then you should see the graphics card (in my case, GTX 97)0 under "Display adapters". Right click the device and select "Properties", change to the "Driver" tab and click "Uninstall". Make sure to select "Delete the driver software for this device", then click okay.
Restart your machine.
Now when your computer has booted you should have generic drivers, meaning your display resolution will be quite small. Now using the files we downloaded and extracted, run the installation now.
If all went according to plan your drivers should have installed correctly and now you need to restart your machine, after the restart you should be all good to go!
