First step was to change the EFI bios and disable the onboard video - 
once this was done I rebooted and the two nvidia cards (nouveau driver) 
came up just fine and I am writing this from the now working system.

Problem is - I want to have my third monitor work as previously. What 
steps should I take to determine the problem. I checked RH reported 
faults for this kernel and someone had a xorg problem but in their case 
it was nouveau not booting - the suggested step of adding 
nouveau.modeset=0 to the boot was tried but as expected made no 
difference to my situation. It is my onboard intel that appears to have 
a driver that needs or received an invalid argument.

Any help appreciated
