An NVIDIA kernel module 'nvidia' appears to already be loaded

I’ve followed all of the upgrade instructions I can find but continue to get the error "An NVIDIA kernel module ‘nvidia’ appears to already be loaded in your kernel. blah blah blah

Losing my patience with this one as I’ve already lost two days chasing it. This is the fourth fresh flash of the latest image on the website, updated, upgraded, expanded etc. Anyone else seen this issue when trying to update drivers?
