Screen remaining black after a forced shutdown

I shut down my computer by holding the power button for 5 seconds and cleaned my computer's fans with a sterile wipe. When I turned my computer back on everything seemed normal until I looked at my monitor. Now the monitor has 0 display and restarting it does nothing! I am on Windows 10 with a custom build.

 

Is the monitor's power cord connected securely at both ends?

Is the monitor's video cable connected securely at both ends?

Is the monitor turned On?

If still nothing, does the monitor work when connected to another computer?

 

I just resolved this myself, I have a decent knowledge but just didn't take time to think. I unseated my gpu when I was cleaning somehow. I really appreciate the speedy response time on this site though and will likely use it again.
