I need to get 2 video cards working. Each video card works fine if only installed alone. Once i add 2 or more video cards in the system the primary video card is the only one that works. Device manager says that it can't install the driver. This doesn't make any sense becuase the secondary video card works fine if you make it the primary video card. I am running build 6001 Thanks,Jim

same thing happen to me let me know if you find out the fix thanks
