I have purchased an ATI Radeon x1050 video card to install to my msi K9AGM2 motherboard. The motherboard has an on board ATI video card and when I plug the new video card into the PCI express slot the coputer won't boot up at all. I have read right through the motherboard manual in setup to see how to turn off the on board video card but I can't find it. Has menu to turn off usb controller, LAN controller, IEEE controller etc. I found a setting to select primary video controller but when i go into set up it already list PCIE as the primary video controller which is the slot i plug the card into. Computer runs fine with out the new video card but won't boot at all with the new card installed.
