hello. i just build my first system out off brand new parts but when i turn it on there is nothing on the moniter. it just says "no signal". but fans are spining and my motherboard lights up. i have tried to take out the gpu and then start it but the same happened when i switched the ram sticks to the different ram slots.

specs: intel i3 7100, xfx rx 480, msi bazooka b250m, evga 650 gq 650 watt, ram kingston ddr4m,
