I am doing a new build. I bought an asus tuff x570plus motherboard I have installed it it turns on the dvd thing works and the hard drive works. it has ram like 8tb plus one of those other little stick things. I put in a cpu the fan on it comes on. When I try to get a screen I get nothing I hooked and HDMI cable to it and its not sending so I cant do any updates or installs because I cant see a screen. HEeeeeeeeeeeeeeeeeeeeeelp
