This is a dumb question I feel like but idk it’s worth a shot, so I got this pc like 3 years ago it worked great, I moved and 2 years later never used it until now I finally plugged it back in and the hdmi won’t work I don’t understand computers at all and my ex boyfriend built it for me (he was evil dw guys) I’ve tried the 2 HDMI plug in on the pc and the 2 on the monitor and I’m just not understanding
