Graphics card wasn't recognized, now monitor won't display

Hello,

I recently moved my computer from my apartment back home for the holiday break. When I arrived and set it up, none of my games were recognizing my graphics card (msi gtx 970). I tried updating drivers, unplugging the graphics card and reinserting it, taking out the ram and putting it back in but nothing changed. I read somewhere that I could use some program called DDU to uninstall all of the nvidia drivers to get a clean reinstall and this is where the real problem began. I clicked to allow the program to restart my computer, the computer turned off and now every time I turn it back on, the monitor stays completely black. Everything else seems to power on fine, the LEDs light up,fans run etc. At this point, I'd just like to have my monitor work :/ Thanks for reading guys!
