Was exactly what you said. Called PCS up and walked me through general troubleshooting, tried to reseat the graphics card still wouldn't work. Was investigated and there is a fault with the DP & HDMI ports, it doesn't recognise which port to go on to so it beeps then finds the correct display. Put my old Graphics Card in and it worked wonders, no beeps. Will have to see if they are able to replace it as it's still under warranty, if not it's a perfect excuse to just upgrade. Just thought I'd give you all an update.
