Black screen not booting


check both your power and video connections to the monitor, sounds more like a monitor power issue.
if the connections appear ok, but screen still blank, try connecting a known good working monitor from somewhere else and see if it works with your pc, if it does, your original monitor is faulty, if it doesn't, you have a pc video issue.
