First PC Gaming build, No visuals But everything turns on, Except GPU.

Everything turns on and SEEMS to be working, but the Graphics card fans dont go on, giving me impression its not on at all. I plugged keyboard in to see if i could make BIOS come up, but nothing happened after aimlessly mashing buttons for five minutes. As for the GPU, i do not know how to plug it in, as there is no where to plug it in. or where to plug in the PC-I cord on the power supply to. Or all of the other cords that dont look like they go anywhere on the Motherboard. But besides the GPU, everything SEEMS to be working. However the front of the case was blinking red, and what looks like a battery symbol was blinking. I have no idea what this means. everything in the build isnt over the power limit the supply can take, so that cant be it. By the way, i am using the stock fans. The fan i baught i couldnt find anywhere to fit it, in fact it doesnt look like it could fit anywhere. Fans arent much of an issue, but i hope nothing is wrong with any of the parts. I hope im just stupid, and missing somthing. By the way it is not the monitor, i tried that with my laptop and it works. I am using HDMI by the way. I heard HDMI isnt very good for BIOS, but i really would rather not buy a specific cord from the internet, and have to wait another week for my computer. ANYway. Some help would be greatly appreitiated. I hope this is the right place to post this. if not, just tell me where.
