My Hackintosh doesn't work with my new monitor

Hello, I have a hackintosh that I built in in 2017 I think it's either on sierra or el capitan I am not sure. It's a 7700k, z270 aorus gaming 5, 1060 6gb. I updated recently to a 240hz monitor and ever since then I have not been able to boot up my mac without it just not sending a signal to the monitor. Maybe it's because I updated the drivers for my graphics card? I honestly don't know. Really I built this machine with the help of a professor in college and I never learned much about how the system actually functioned I just know that it worked. All I know is the mac boots up it shows the boot logo on my second monitor (HDMI output) and then it shuts off the monitor and never comes back on. There was one point a few months ago when I could get it to boot into the os for a few minutes before the monitor shut off but I haven't been able to use it since then. If anyone has any ideas I would greatly appreciate them. Thanks in advance.
