I recently had a problem with the nvidia-340xx.  I would only get a blank screen with no X
being started.  I did not check the logs I just did what has worked for me in the past. 

1.  dnf erase *nvidia*
2.  reboot   (You could either boot to gui using nouveau or multi-user mode)
3.  dnf install akmod-nvidia-340xx   (In your case akmod-nvidia-304xx
4.  reboot

There is nothing to lose by trying this.
