Found out the problem. I'll leave the answer here for anyone else who has the same issue:
HDMI original port to the monitor shared something with the old graphics card, and where it was hooked into. Switching to another port solved that issue. (move from hdmi port 2, to hdmi port 1)
The second issue happened when turning off the computer during windows updates, which caused the error to not install drivers properly. After applying the updates fully, and making sure all updates are accounted for, the drivers were able to be installed without issue.
