Power off. Move video data cable to MB port. Power up. Go into the BIOS during startup. Change video back to integrated. Continue into Windows.
Remove card's drivers. Power down. Remove card. Power up.
That's the general idea
How do I get to BIOS and change video back to intergrated? that is the part I dont know I have no knolwledge no how to get around BIOS and its a bit hard to even see the text because of the artifacts.
