I just finished my pc. Yay. I turn on the powersupply, it's fine. Motherboard power light and graphics card light turns on. Press power on the case fans spin, glow up yadayada. Then when I turn on my monitor and switch it to hdmi and press the delete key like a maniac it says " hdmi no signal". Any ideas? People here said for similar issues it's the ram but I want to see whether for my case it's different. I have an asus z170-e motherboard and 16gb 2400 ballistix single ram stick. On pc part picker they said it was compatible so idk wat to do now.
