New build. No ssh lead to no webUI lead to no bios?

[cmalec]

Few days ago booted up a fresh built tower with my fresh unraid boot stick. Everything spun up and worked fine. set up the array and some cache pools. started migrating some data with rsync. Everything going fairly smooth til i realize I can't ssh to the tower. Try to reboot but then I couldn't get the usb drive to be detected that lead me to flipping the bios setting for CSM on/off and got the boot stick back. Got back to the webUI but still no ssh. Poking around setting accidentally switch on ssl in settings>access management and lost the webUI. Shutdown take out boot stick plug it into laptop and turn off ssl via config and turn on ssh setting in config. Also delete ssh and ssl folders as mentioned in other threads on a way to fix lack of ssh. 

Now when i try to boot up i get nothing. machine seems to start running but nothing goes thru to the monitor so just 'no signal' message. but keyboard and tower light, fans spin so things are working. But also nothing seems to boot the tower never seems to get back its IP or be available. 

So assuming its gotta be the motherboard(asus prime z590-a)/bios but everything was running before so some setting i changed? Any ideas?

Any way to revert my unraid settings while keeping the array data intact? Also trying to see is there a way to reset the bios settings. 

Open to any other options or things to try.
