    Hey guys,

    I have a 680 flashed in my cMP I haven't turned it on for a while but I went to boot up el cap and it gets stuck half way on the loading screen. I put the GT120 and it loaded in then I installed Sierra and put the 680 back and the same issue is arising.

    I unflashed the card and same thing.

    Any help would be appreciated

    thanks
