did complete uninstall of AMD drivers and notes with no video out. I am concerned with red light on motherboard with 3060 installed.
When you did this did you follow the directions Bizman posted? That's the only way to do this when changing cards physically. ESPECIALLY if going from team red to team green or vice versa. YOU HAVE TO use DDU to get rid of everything FIRST. This automates removing a bunch of stuff in the registry you might have a hard time finding if you didn't know what you were doing. Great app. Totally trustworthy.
If you haven't done that, I'd suggest:
Put the AMD card back in. Hopefully there aren't too many knots in it with Windows by just swapping cards and your machine will boot up.
If it does--great.
Download DDU from the link Bizman posted. Unzip it if needed.
Download the latest drivers for your 3060 from NVidia
Have them somewhere you can get to easily like the desktop and ready to go.
Reboot the PC in safe mode---this is important.
From safe mode, run DDU.
Follow the prompts, select AMD graphic drivers.
Select clean and shut down. The PC will shut down.
Swap out your cards.
Disconnect from the internet. Unplug. Whatever. (so windows doesn't install a driver on you quickly)
Restart the PC in normal mode.
It should act as if it's never seen a video card before and you'll have a low res screen.
From here run the NVidia driver setup you downloaded.
This should straighten you out.
Unnless your card is actually DOA and lets hope that's not the case.
