Ive just finished my first build and all was going well until after i installed Windows 10 and put my GPU in. My motherboard is a Gigabyte 78LMT-USB3 and my GPU is a Geforce GTX 750i. From what Ive read (on this site and a few others) they are both compatible. Everything works right, the fan is running. No extra power connectors so its not that. Ive tried re seating the RAM in different slots and that didn't work. The BIOS is up to date. I tested the display on my tv(HDMI) and my monitor(VGA) and both work fine without gpu. I used the HDMI on the gpu and nothing. Please someone help this is driving me insane... :??::fou:
