I have a mainboard of a MSI 2AE0 that have with built in AMD Radeon HD 7560D. I want to replace the built in video with an external EVGA GeForce GT 610 2GB DDR3, DVI, Mini HDMI, Graphics Card. If I just try to swap it out the computer won't boot. What do I need to do to disable the built in AMD Radeon HD 7560D and enable the EVGA GeForce GT 610 2GB DDR3, DVI, Mini HDMI, Graphics Card. Any help would be appreciated.
