I removed the graphics card and SSD before shipping it across the country. Now my new monitor wont display anything. We tried plugging in my computer into my roommates monitor and it didn't work at all. Its not my monitor as I plugged it in with my roommates desktop and it worked fine, we also plugged in his graphics card into my computer, but that also didnt work which means it's probably not my graphics card, and probably something in my motherboard, but I have no idea what. Everything seems to be plugged in properly. Tried DVI in both the motherboard and the graphics card, tried VGA and the DP port with no luck.
