That might be what it is...I did forget to uninstall the nVidia drivers before removing the card for the first time. Don't know why I didn't think to do that. Of course, it's not like I can go back and fix it; my monitor won't even read the video card; I can't even get a picture or get my keyboard to work, let alone access my BIOS or my nVidia drivers.
I supposed I could try resetting the CMOS battery again and try running on integrated graphics alone.
And to my knowledge, everything is plugged in where they should be. I just don't understand.
