Alright, plugged them in one by one. I got up to the third card. When the fourth was plugged in and the system powered on the screen came on. My mouse without borders didn’t work. I then restarted the machine to get the mouse without borders program to work. Upon restart black screen… So I then power down and unplug the fourth card. I start the system again and have black screen. Standby for more information as I restart it again.
Edit: The monitor VGA is plugged into onboard input.
