New Build Won't display signal

[ThePoundDollar]

Can someone please help me. I've just received all the parts for my new build, fitted everything together, and for some reason nothing is being outputted. I did a test before I fitted everything in the case and I got a signal from both the motherboard and video card, but this time there's nothing. When I start the PC up I get that little beep which apparently means everything is fine, so why aren't I getting a signal?

Have you tried straight from motherboard? Does that work?

Sorry to ask this, but its a common problem, check that you don't have one of the motherboard stand off's in the wrong place under the board, this can cause a short and ive even known people to fry their nice shiny new boards with a stand off left behind from the old board that they didn't realize was there.

Oh never mind. For some reason, unplugging the video card power supply then plugging it back in fixed it. In fact I'm telling you this from the new build! Thanks though.
