Question Monitor artifracting and computer crashing after hooking up new monitor

Jan 12, 2020
I just bought an Asus ROG STRIX XG248 monitor, and after hooking it up, any game I launched would have purple artifacts fill the screen, lock up, crash to desktop, and eventually the screen would go black or freeze. I have tried an hdmi cable, uhd cable, different ports, and a factory reset, but the same results. It happens on both my new monitor and my old monitor, but only after i hooked up the new monitor. I even tried my old 1060 6gb card, it does not get artifacting, but it still locks up my computer and i have to force shut down. CPU usage and temp is low, ram usage low, gpu usage low, Im out of ideas.
