Hey All,
So my build is straightforward - 6700k / EVGA Z170 Classified (4 Way) / EVGA GTX 980 Ti Hybrid / Noctua NH-D15S / EVGA 1200 PS PSU.

I moved all my parts from a Haf 932 into a Phanteks Enthoo Luxe. Very happy with the new case and all went well.
However, when I started it up, at first it wasn't seeing the SSD drive (Boot Drive) - I resolved this by going into the BIOS and resetting everything. That worked fine.
Then I noticed that the GPU wasn't running ?
 
I should just add that the only differences from one case to the other are as follows:-
1 - I changed from using the normal PSU Cables that came with my EVGA 1200 P2 PSU to the Red Cables bought from EVGA.
2. With the HAF 932 - I had 3 fans ( 3 * 200mm) fans running from the fan headers on my Montherboard. I also had the 1 fan on the NH-D15S running from the CPU1 Fan header and that was it. In the new case, the 3 fans ( 2 * 140mm and 1 200mm) are connected to a Fan hub on the back of the case. This is then connected to CPU_2 Fan header on my mobo and powered by a Sata connection to my PSU. ALl the rest are the same.
 
The card was in PCi Slot 1 so changed and checked in Slot 2. Same issue.
So, Windows 10 isn't seeing the GPU and when I start up the PC, the 980 TI Hybrid fans (blower and one on the rad are not running).
Then I changed the VGA cable for another to test and the same thing.
I then swapped back the original Black Cable from the PSU I was using to test that and same thing, nothing.
I changed the VGA Ports 1, 2 and 3 on the PSU - same issue.

Finally I swapped in my EVGA GTX 960 SC card that is running fine in my kids PC and the same thing.
My thinking is that it's either the Motherboard or PSU ? But what tests can I run ?
I have a question ?? If my GTX 980 TI HYbrid is securely in its PCI Slot and Power cables attached, if there is an issue with the Motherboard but PSU is fine, should power be going to the GPU and the fans kicking in ???
I would test my 980TI in the kids PC but it has an EVGA 430W PSU that doesn't have the necessary power cable for the card.
Any help or suggestions appreciated ??
Not sure what is causing the problems and all was working fone 24 hrs ago..

Hi Sajin,
Thanks for the response. I am going to remove the PSU and 980TI tomorrow and put therm in the Kids PC with an i3-6100 and Gigabyte GA-H110M-S2HP Motherboard and test it.
If the card and psu work fine, I can only assume (as you have stated) that there is an issue with the motherboard.
If this is the case, is there anything I can do on my end before having to send back (last resort) ?
I have already reset the BIOS..
I have removed the 980TI and EVGA Precision and loads up fine - but sometimes giving an error of 5d - which relates to PCI slots I think ?
Regards...Emilio

This is the 1st time I have ever had to return anything via RMA.. Is this an easy process ?

Yes, it's an easy process. www.evga.com/howtorma
 

Thanks Dr Death ..
Yep, I only buy EVGA products now due to their after sales service. I have never had to return something before but a friend of mine had a Asus GTX 770 that started to go wrong when it was a little over a year old. Needless to say, they were anything but helpful. Amazon.co.uk ended up stepping in as he bought from them originally and in Europe, all electrical items come with a statutory 2 year warranty. 
All my current GPU's and PSU's are EVGA - main motherboard is EVGA and even my mouse ;-)
I am currently in touch with tech support. Down my main gaming PC for a week now...just as BF1 was released and the new DLC for Dark Souls 3..ah well.
Thanks again!

that can be true    I've seen where the cpu cooler improperly mounted can put stress on the socket   /warp the board  and cause issues as this ???    crooked tightening  /too tight    then they claim skylake got a thin lid  may bend in to something inside the chip cause a short  ?? [long shot I guess?]   heck MSI offers a guard
