I just got a Corsair 540 Air mid sized tower. This is my first time building a PC. I connected an asus z370 e motherboard, i7-8700k prcoessor, H100 i V2 liquid cooler, 250 GB 960 evo ssd, 2 tb seatgate sata hard drive, evga 650 PSU and a zotac 1080 ti extreme amp gpu. It seems like I got everything connected but my Monitor is not powering up. I tried hdmi, dvi cables, even went and got a new monitor but its not working. I think I might have not connected the hdmi/dvi output to the motherboard? Please help
