Hi, first time user, PC builder, and poster on here. I just built my PC, and without the GPU installed can get it to boot to the BIOS. However, when I do put it in, and plug the HDMI into the card, nothing happens. My GPU is a GeForce GTX 1050 Ti D5 4G, and the motherboard is a GIGABYTE B250M-DS3H. It's a micro motherboard, and the GPU doesn't have it's own PCI-E port for power. Any help at all would be much appreciated.
