PCIE Error resulting in no GUI/ instant freezing after boot

I suggest to install with nouveau driver (free driver) first then tackle the Nvidia driver as @jonathon mentions.

I also had some problems with hybrid graphics.

For the 470 driver here is the relevant info, also found as pinned thread on top of forum :wink:

Edit: if you feel comfortable on tty you could remove the nvidia driver and switch to open source like in my first link, then install 470 following the second link.
