Hi everybody, And thanks for all your help.
I have now fixed the problem, and heres the problem I had and how I fixed it:
Problem:
Existing PC had the old motherboard taken out (Gigabyte GA-K8NF-9) of it and had a new motherboard (ASUS A8R-MVP) put in. After put all the wires and RAM and other card in, I turn on the PC and it all works all the lights come on all the fans come on etc but I got nothing coming up on my monitor even though it was pluged in.
I put back in - all my four sticks of RAM, my graphics card, my CPU, my sound card and all the wires.
How it was fixed:
I took everything off the motherboard apart from the CPU, then I put only the bear minium on the board this being, 1 stick of RAM and my graphics card, and all the wires (duh). I turned the PC back on and I got the 1 beep post I'd been waiting for, 1 eep means everything is working correctlyand nothing is broken or unpluged. I then installed and uninstalled all the stuff I needed to, and put all the things back in including my sound card.
So whats was wrong:
The BIOS didn't seem to like all four of the DIMM slots being taken up or my sound card or it was both.
