Any idea why you have AMD drivers installed, see below that I have highlighted in red;

Anything ATI or AMD needs to be cleared from your computer to avoid driver conflicts.
A clue that all is not well is the following from your OP;
I haven't touched the graphics card at all and it is still in my computer however it does not show up in the device manager.
When an add on video card is detected by the BIOS the integrated video ports are disabled by default, this even if the add on video card is not working, this can be overridden in some MBs BIOS settings and being that you have not removed the card but are getting a display from the onboard video ports it would suggest that this may have happened here, to check this possibility, restart and go into the BIOS then restore the MBs default factory settings, save the settings, shut down, connect to the add on video card, restart to test.
Going offline now so will leave you to do the following as well;
Download then run the Windows All in One Repair (free) from here, disregard the malware guidance but follow the other steps to the letter and in particular ensuring that you first create a new restore point and perform a proper Windows clean boot before running the repair, details for the clean boot here.
