Evga 1070sc not working on b85 d3h

[nguyenviet191291]

Hello guys,
I’m currently using b85-d3h rev1.1 mobo, with a gtx 770. Yesterday, i have bought an evga gtx1070 sc. I’ve installed the new gpu, but it cannot be recognized, the pc only runs onboard graphic. I tried put back the 770 and its working ok. Tried to update my bios, but situation is the same. I also tried to install it to my friend pc and it also works ok. Pls help ! Thks guys

Please post your full system spec.

When the 1070 is installed, does the onboard iGP still work? Have you connected power to the 1070?

Have you tried clearing the motherboard's CMOS?
