just blows my mind that my evga gtx 980 sc acx 2.0  after 3 years is still working
I took out the kingpin and put my 980 back in  and it is working so the kingpin kicked the bucket.

Well what exactly is your issue?
Check your DP cable first and try another mini display port, those tend to be unstable. If I touch the cable it can easily lose connection and the monitor goes black. Try a Cmos Reset. Try to boot into windows save mode.
When I first swapped my kingpin in and removed the FTW3 I had all kinds of weird issues with black screen and unable to get into windows. And almost always a reinstall of PrecisionX is required, when swapping cards.

both MB and VGA had updates Asus EZ-update was not showing them had to install manually both cards are working

there is no longer any issue all 3 GPU's work in the PC both 1080 kingpin's and the 980 SC if it was or not the update for the BIOS or the VGA i don't know it is working so I am happy  

That's really odd. The card was working fine for 3 weeks then out of the blue it just stops working. Now it's working again after updating the motherboard bios, and the gpu vbios.
