So I've just recently built a new PC windows 7, i74770k, Asus Maxumis IV, 16gb ram, HD 7850 2gb. The on board video works but when I install the new HD 7850 2gb card I get a black screen and a VGA error code on my motherboard. This card is brand new out of the box. I have tried to get a hold of tech support but they seem to be closed during business hours. IDK whas going on need some help.
