I recently purchased a B stock GeForce 1060 and tried to install it in my Dell XPS 8700 (32 GB RAM, intel i7, A14 bios, GeForce 645). I initially got a black screen and a CMOS chksum ROM error followed by infinite re boot loops. Based on a suggestion I removed the motherboard battery Andre-set the BIOS, but I still got a black screen. I realized I was running legacy BIOS and switched over to UEFI, reinstalled the card but I am still getting a black screen and reboot loops. I figured I did not need to run DDU since the previously installed card used the same drivers and they should work with the new card. Does anyone have any suggestions?
