OMEN by HP Desktop PC - 870-224

This morning everything worked as it has for the last few years. But then I go get a new desk, so I unplugged everything to get the desk set up. When I finish the desk I plug everything back in and get it all set up the way I want it and low ans behold, I get a "no signal" message on my screen.

 

I've tried 4 different TVs (as I do not own a monitor) and 3 different hdmi cables. No combination of any of them are working. 

 

After several hours of head scratching and blood pressure medication, the only thing I can find on the internet to help is to upgrade my drivers (which I probably haven't done in a long time), but how do I do that without a visual component?

 

Please help me. I'm falling apart over here.

 

Thanks.
