Hi, I'm using a Gigabyte motherboard GA-Z77M-D3H, it has a PCI-E X16 slot, I then bought a Gigabyte GTX-1070, after I slot the 1070 in the X16 Slot, I can go to the BIOS screen and the screen went black out while the Windows was keeping booting up normally. [I slot my old display card in the X4 slot and awore of that. What can I do??? Please help!!!
