This is my first time building a PC and first time on a forum such as this and I'm probably about to ask a stupid/silly question, but I had finished putting my build together, plugged it in and turned it on and everything seemed to be working. However when I connected it to the monitor via HDMI the monitor did not receive input. I used two different cables to rule out that it wasn't the cables fault. I also had a usb inserted with the windows boot, just mentioning in case that helps with troubleshooting.

Anyway sorry for the perhaps stupid question. I just want some advise... and kinda don't want to have to take everything apart if i don't have to.
Thanks to any of you who reply
