Hi

I'm really hoping someone can help me with this really annoying issue.

My Rig :

XFX XTR 1050W Black Edition 80 Plus Gold Modular Power Supply - Black
Samsung 1.0TB 850 EVO SSD 2.5" SATA 6Gbps 32 Layer 3D V-NAND Solid State Drive (MZ-75E1T0B/EU)
Samsung SM951 256GB M.2 PCI-e 3.0 x 4 NVMe Solid State Drive (MZVPV256HDGL-00000)
Asus Maximus VIII Hero - Intel Core i7 6700K @ 4.60GHz
Corsair Vengeance LPX 16GB (2x8GB) DDR4 PC4-24000C15 3000MHz Dual Channel Kit
Asus GeForce GTX 1080 DirectCU III Strix Gaming Aura RGB 8192MB GDDR5X PCI-Express Graphics Card
Microsoft Windows 10 Pro 64-Bit

So to start off with I bought a pre-overclocked OCUK bundle so I'm assuming this is ok - My system was running fine until I put in my new 1080 (Had my old 970 in it until this was delivered) now when I boot up everything seems to power up fine my keyboard lights up and mouse - but my monitors say no signal. The only way I can get round this is by using the reset switch on the mobo 2-3 times then it boots up fine. I have re - installed Nvidia drivers but I didn't think that would affect the bios not posting on the screen. the only thing I have noticed is that the PCI is running at x4 but I think this is due to the M.2 SSD. as I say when it finally boots up it seems to run fine.

Any ideas ?

Thanks in advance

Sort of

I installed the new card and updated my GFX driver and selected the clean install option - I have since uninstalled and reinstalled the driver but as I have said above I wouldn't have thought the driver would affect the post ?

Also, I have Arc for Logitech on my phone and I tried logging into windows 10 with my monitors blank and Arc reported my CPU and Ram usage but the GPU was blank so this suggests that its not reporting to the system as present.

I have also checked its seating on the on Mobo and noticed its touching the north bridge heat sink so I wonder if that's the problem but I wouldn't know how to fix that if it is but this would be annoying as the only reason I went with an Asus GFX was because I had an Asus mobo so I stupidly thought it would be compatible within its own ecosystem,

Both led light up in white and I noticed when I took one out it went red so I assume that its getting the correct power - What do you mean by different PCI-E connectors ? power plug or mobo connection ?

Thanks, if I had any hair I'd be pulling it out, also would know if the x 4 on the pci would be a problem or is it still enough bandwidth for the 1080

I have it in a x 16 slot but it say x 4 on the bios but I think this is because the m2 ssd uses some of the resource

Yes and this was the problem maybe it's a faulty PCI lane or something but even tho my 970 worked fine this just doesn't so I have switched it to the 8x PCI lane and it works fine, so this will have to do for now I guess I still think its to do with the clearance on the Northbridge heat sink and SATA ports as these are raised but other than milling out the heat sink and ripping off the SATA port I can test my theory.
