No boot, Alienware screen after GPU upgrade on Aurora R7

I recently purchased a Radeon AMD RX 6600. I know that I needed more power to run this in my R7 so, I installed a 750W gold Seasonic. PSU upgrade was successful. After installing the new GPU I get to the Alienware screen but can't get to windows, nor can I open the bios menu.

I've tried using DDU to uninstall all of my NVidia and AMD drivers. I've disabled fast boot from the bios after re-installing the factory 1050 ti and then putting the 6600 back in. Within the bios I don't have any pcie options available to me. Not sure where to go from here. Anyone have any ideas?

Looks like you will have to disable secure boot, possibly enable legacy CSM mode.

You would have to put your 1050ti back in, access the BIOS screen and see what options you have available in your BIOS.
