GPU won't post

[areoace]

This is my first time building a PC and I just can't seem to fix this issue.

Specs:

Intel 6700k
MSI Z170A mbo
16g Kingston ddr4
H100i gtx liquid cooler
Phanteks enthoo luxe case
Gigabyte 980ti
EVGA 850g2 psu
EVO SSD
3TB Barracuda

I suspect it may be a power issue because the computer works fine without the gpu installed, however when I install the gpu it powers up from the mbo but when I plug cables from the psu in or out nothing changes.

I hope from your post you didn't plug/unplug gpu power with computer on?

God no, I meant with the power off

Update:

It didn't work when I tried a different pci slot

So I eventually got my mbo to read it once but then I had to move everything around because it wouldn't power on after I shut down (I moved the 24 pin on my mbo?) and now I back to the gpu not being read.

My mbo lights up the dram sign, but vga won't light up at all with my gpu.
