Nvidia GPU driver errors

After Windows10 update Nvidia GPU driver corrupted. You can find driver downloads in Nvidia website (http://www.nvidia.com/Download/index.aspx)

Setup may not continue for some reasons. 2 errors described below.

Error1: Windows cannot verify the digital signature for this file

Disable enforced driver signing Run command line and type
shutdown /f /t 0 /r
Press "F8" and continue.
Click ‘Troubleshoot’.
Click ‘Advanced Options
Click ‘Windows Startup Settings
Click Restart.

After restart select ‘Disable driver signature enforcement‘ from the list by hitting F7. Then continue to install driver after Win10 booted.

Note: The shutdown command does not work in a RDP/Termial Session, otherwise error “The parameter is incorrect.(87)” occurs.

Error2: The graphic driver could not find compatible graphics hardware || Nvidia installer not compatible with this version of windows

Exit setup.

Go to Device Manager > Display Adapters > Select device from tree > Right click and select Properties
Go to Device tab > Select Hardware Ids from Property list
Copy first line (PCI\VEN_10DE&DEV_1BE0&SUBSYS_75071558&REV_A1) and quit

Go to Display.Driver folder which extracted from driver setup.

Open nvami.inf

Find NVIDIA Devices line: [NVIDIA_Devices.NTamd64.10.0...14310]

You will see many lines like below:
%NVIDIA_DEV.0DCE.204C.1043% = Section002, PCI\VEN_10DE&DEV_0DCE&SUBSYS_204C1043

Copy first line until PCI word: %NVIDIA_DEV.0DCE.204C.1043% = Section002,

Paste it to new line above copied line (under NVUDUA_Devices line) and then past hardwareId copied from Device Manager

%NVIDIA_DEV.0DCE.204C.1043% = Section002, PCI\VEN_10DE&DEV_1BE0&SUBSYS_75071558&REV_A1

Do same thing for the line [NVIDIA_Devices.NTamd64.10.0]

You will paste 2 newlines in total to nvami.inf file.

Save inf file to original location and run setup again.


As of 23rd July something changed on Windows 10 and Nvidia setup. Check updates below.
1. If you can't reach Advanced Startup menu then lock your computer. While pressing shift key press power icon on screen and select Restart.

Package install status code: Exception {0x800f024b - The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering.}.
3. Update Windows 10 to the latest version.
Check your version by typing winver to Windows search box to see version. Your version may be older than driver supports.

Install driver from inf file.

Press "Let me pick from a list..." option.
 Find your device in list.

Press "Have Disk" button and find inf file.
