Update:
Hardware is working fine.... apparently always was.
After reading though trouble shooting forums, I found out that you have to connect through the Display Port until you install software in order to display on the screen. And you have to do it through the GPU because onboard will not work with the Ryzen 7 (or something like that....)
So I had to move upstairs to the carpeted part of the house, and test it using the monitor there, as that was easier than dragging a different monitor and cable all the way down stairs just to test the system out.
Now I have to figure out how to get Windows 10 on the computer.
hopefully a much simpler problem. Also bought the additional SSD for no reason. The M.2 was connected and working properly. I just couldn't tell because the display didn't come on.
Also the Liquid cooler wasn't as complicated as I thought now that I figured it out.
The video tutorial made it seem over complicated and the booklet it came with wasn't much more help. Now that I know what is needed, it really wasn't all that complicated after all.
So onto the next mission... Windows onto a USB Drive, and attempt to boot from there to install onto the M.2
So I actually have to pay for Windows now, huh...? :/ $100 for Pro version on a USB stick.
$140 to download it myself, and $199 straight through MS.
edit: Oh, and when I have the 2nd RAM Stick in, the computer won't display, so it was the RAM.
not sure if they both have to be in the DIMM2 slots or not.... I might just check to make sure it was in all the way, and then see if I can make it work on DIMM1 slots, otherwise, gotta make an exchange.

Final edit: all is good. All hardware working fine.
Windows installed, just need to get the key... Hopefully I can use my existing one from another computer.
