I am not sure what the meaning is here. Have you installed 4 different times on the same computer? Or are you installing again and again without removing the older installation? Or as you note are you doing something like installing f39, then upgrading one version at a time to the newest (f43).
In order to address your issues, I strongly suggest that you first install f43, totally new, then work from a known good point to address the other issues.
It is vitally important that we are able to understand the details of any issue you report, and that we may be able to test a similar installation in order to assist.
A good starting point is this
and how to ask for help should be similar to this
Installing the nvidia drivers when you have an nvidia GPU should be done by
- enable the 3rd party repos during the first boot setup process.
- install the nvidia driver as shown here
- It may be necessary during the initial install to use the
troubleshootingoption on the very first screen of the install media boot and use basic graphics to perform the installation before the drivers can be installed. - Remember that the very first boot after installing the nvidia drivers may need secure boot disabled and if you wish to use secure boot the instructions on how to do that will be in the file
/usr/share/doc/akmods/README.secureboot(or at this site)
