@Plec - I have a working PC now
The new motherboard and CPU works a treat and the new cooler and no graphics card make it so much easier for me to sort out the various wiring.
I did test the 980Ti and it works fine but have gone back to on board graphics.
So it looks like it was the Asus X99 that was faulty.
Thanks for all your help.
