PC won't link to new Dell monitor

Just bought a Dell U2412M monitor. Setting up it says no signal from the PC

I've tried 2 DVI cables and then the VGA from the old monitor. The old monitor (VGA) works fine but the new one still says no signal when I swap it to the VGA cable.

Tried to use the setup CD with both monitors connected but it wont do anything until the Dell gets a signal.

I have been using the input buttons to change between DVI and VGA so that's not the reason

Any suggestions or is it a faulty monitor?

Can you try to connect it to another PC/Laptop? If it still fails then it would look as it would need returning.

It receives a VGA signal from a laptop. Still nothing from the PC

OK. So the monitor works. At the rear of the PC are there two sets of video outputs? You might have a dedicated graphics card installed and that will disconnect the motherboard's GPU output. Something easily overlooked. You might have connected to the wrong port, possibly.
