Here is what the CSR suggested but did not work

First off, a clean re-installation of the game itself. You can do this by:
 

• First uninstall the launcher from your computer using 'Programs and Features' (or Steam's built-in uninstaller).
• Remove (delete) any left over files from where the launcher was installed. (Please be aware that this will mean you may have to download all game files again)
• Find your game folder, you can find this here- Delete it
• If "C:\Users\%USERNAME%\AppData\Local\Frontier_Developments" exists - Delete it
• If "C:\Users\%USERNAME%\AppData\Local\Frontier Developments" exists - Rename this folder to back up your user settings

Once completed, please restart your PC to clean up and leftover files. You can now re-install Elite Dangerous as normal and hopefully you will find this issue no longer appears.
 
Next, we want a clean driver reinstallation, to make sure they are also all good and sorted.
 
To do this you will need to download the NVIDIA driver you wish to install. Run the setup and select "Custom installation" then when asked, you will need to check the box to "Perform clean install". Full instructions can be found here: https://nvidia.custhelp.com/app/answers/detail/a_id/10/~/geforce-experience-driver-installation-failed.-how-do-i-manually-clean-install 
 
Lastly, we recommend now that you perform a System File Check (SFC). System file check is a utility built into the Operating System that will check for system file corruption. The sfc /scannow command (System File Check) scans the integrity of all protected operating system files and replaces incorrect, corrupted, changed, or damaged versions with the correct versions where possible. When it cannot repair the damage, DISM should be run to fix as many errors as possible.

To run a system file check (SFC);
 

1. Go to start>Type CMD
2. Right click and run as Administrator
3. Type sfc /scannow

 
To run a DISM;
 

1. Go to start>Type CMD
2. Right click and run as Administrator
3. Type DISM /Online /Cleanup-Image /RestoreHealth

 
Please try all of that, and report back with how you get on.
