Have you tried both PCI slots?
Yes on 2 boards as well. What I can't get my head around is that I had an r5 1600 with an asus b450 motherboard I think which worked fine never had an issue, I disassembled the motherboard because I had sold them on ebay so had to ship them and the rest of the parts just sat there for 3 days until my intel cpu and board arrived, now the gpu just doesn't get a signal anymore
 
Do the fans spin on the GPU?

In device manager does it list the GPU ever being there?
May have to select show hidden devices.

How was the GPU stored while you were waiting for new parts?

Yes the fans spin and the card was left in a cardboard box. The pc is not detecting the card at all I've tried show hidden devices and it still won't show up but like I said I've had it tested and they confirmed it working so it's definitely not broken
 
The only other thing that I could find that may be causing the issue.

Are you running the GPU in SLI

@Bruce
 
as stated in post #10, it would be good to know what type of mobo, and PSU, the shop used.
the card only stopped working for your new mobo, it worked on the old one and on the shop's one.
for some weird-arse reason, it seems that card doesn't like your mobo.
don't know why, never heard of it happening before that I can recall.

or there is a slim chance your PSU is the reason.

granted - all theoretical but that's all I've got - sorry!

Yes it is very strange. Thanks for all the suggestions. I will update this post if I get it working again
 
yes please do.
did the shop charge much when they tested the GPU in their system?
did they only use your GPU or did you give them your whole rig?

I only took the gpu down and they only charged me a fiver, he did say as I was leaving I could bring my pc for testing if I couldn't get it to work but I know he'll want to keep it for a few days and I'm not sure what he'll charge, I've been out of work for a few months so really don't have money at the moment
 
PS: EVGA 600W BQ

How old is this.

The GTX 1080 is a high end card and so needs the stability of a Gold efficiency rated PSU, Bronze are only any good for integrated graphics or at most an entry level 64-bit type card, not saying that it is definitely the cause but the extra wattage required by the new system could just be a little too much for the PSU.

When the gpu is connected the fans spin and it's booting into windows with a black screen I know this because the second I switch the cable into the igpu it's already on the desktop

This is odd, when you have an add on GPU in the board when you power up the BIOS should detect the add on video card and by default disable the onboard graphics, this whether or not the add on video card is working.

Check in the BIOS to see what is set as the Primary video device.

Power supply is around 4 or 5 years old. It is set by default to detect an external gpu in the bios. Also someone else suggested it could be the psu but if it is I'd be surprised if it could power a 9600k without issues, what is your opinion on this?

The present PSU from new only had a three year warranty so may be showing it`s age ** the fact that it can power the 9600k doesn`t come into the equation until the GTX 1080 is in the board, this because even the none Ti version of the GPU ** requires almost twice the wattage that the CPU does and that is when the processor is under a full load.

** The none Ti version of the GTX 1080 only requires 1x 8-pin supplemental power dongle from the PSU, specs here you mention that your GPU requires 1x 6-pin + 1x 8-pin, this suggests to me that you have the Ti version which requires a minimum of a 600W Gold efficiency rated PSU, the Ti version also requires more than double the wattage that the new Intel CPU requires, 250W to be precise, you can confirm this for yourself here.

It's a 1080 but maybe an overclocked version. I am soon to start a new job so I will buy a much better psu and get back to you
 
You could be right, a bit like some MBs have an additional ATX power supply for overclocking k CPUs

A better PSU is in order in any event, just be sure to go for a Gold efficiency rated PSU from a proven brand such as Corsair, EVGA or Seasonic, disregard anything from lesser quality well known brands, you can tell these by the warranty period, you want seven years minimum but if available within your budget go for ten years.

Okay thanks. It may be a week or so but I will update this post once I've received the power supply
 
You are welcome and fwiw the Seasonic would be my first choice because of the extra wattage.
 
To avoid us having to ask for an update every couple of days we will close this thread until the OP has the time available to work towards resolving the issue, PM a member of staff when you are ready and the thread can be reopened.
 
Received via PM from lfcben;

Hi, to my surprise a new psu did get the card working again, I wonder what happened to it when it was out of use for a few days? Strange

Not really a surprise or strange lfcben, as was previously suggested the old bronze efficiency rated PSU couldn`t support such a high end GPU.
