So im having an issue with my new msi b75a g43 motherboard , everytime I connect my gtx 1060 even if it isn't connected to my monitor my pc will post to a black screen with "b2" in the bottom right corner , ive tried updating my bios but everytime I try it , it says theres no bios file on my usb , it works fine with the onboard graphics so I know its not my cpu causing this
