i have completed my new computer build and set everything up but when i go to boot it the case lights up and the fans spin but my monitor isn't reading the computer at all. i tried with an hdmi cable to use my tv to check if it was just the monitor but my tv doesn't pick up the computer either. at first i thought it was my mother board but i went over one of the tutorials here and with that it appears that all my cases wires work now as well with my led light coming on and the cases fan spinning so im not sure if the gpu is the problem or something else.
