I just built my system and was waiting for that dreaded time when you hit the power button and ou hope it come on. Well everything came on from what I could see other then when it is hook up into the monitor the monitor says no video input. I have two defferent veido cards and have used both with both saying the same thing. No video input. Is there something wrong with my system could someone help me on what i need to do or just start sending stuff back.
