I bought the card yesterday, and have tried to set it up for hours. I have the power plugged in and the card connected to the MB correctly. When I plug in the power supply the screen is black and has no video but sounds still works. If I don't plug in the power my old VGA connection still works and I can view the video on my screen again. I have read like 20 different blogs trying to disable my onboard/ integrated chipset. I have done that with no luck and I am getting very frustrated. Please Help!
