Just built a new system and I'm having quite a mysterious issue with getting a video signal. All of the components are getting power and seem to be working as they should but when I boot the system my monitor gets no signal. Thought maybe the gpu was bad so I plugged in a good gpu and still got no signal. So I tried using a different monitor and dvi cable and still got nothing. So I've ruled out the it's a dead gpu or cable or monitor so my next thought would be that maybe the mobo is a dud. This is the first time I've tried to boot it so I don't have an OS on it yet and nothing has been done with it. Everything is fresh out of the box. I'm also getting no beeps from my troubleshooting speaker so I really don't know where to turn next. Any thoughts?
