GTX 970 cannot be ejected

[Katsuro]

So recentlly I've got my new PC, it's self build (or parts are chosen by me) and I put my GTX 970 in it. It has weird behavior that started out of nowhere, showing this error when playing:

This error can be seen, but my screens turn off and I can not turn them back on, or get any picture with it (I screenshotted it). Also the Desktop Window Manager crashes on start up if that helps any of you..

Hardware:
Intel Core i7 - 5820k 3.3GHZ
Corsair LPX Vengeance - 32gb
Asus X99-A
and the Geforce GTX 970

I really hope any one can help, I am really breaking my head over this.

Thanks in advance!

Good news, and bad news. The good news: you are not alone in the issue, even though it is rare. Bad news: there doesn't seem to be an official fix for it from Nvidia as nobody can pinpoint the issue other that it occurred in recent driver updates for removable external GPUs. See this forum from several months ago:

It appears Nvidia tried to fix it with a Hotfix back in February in this article (link to Nvidia hotfix at the bottom of the story is no longer valid). read the comments at the bottom to get more info and a possible registry fix:

Well, since you are getting a video signal we know that your 970 is seated in the pci slot correctly. It sounds like a driver issue to me. Check your bios settings, make sure the video output device selected is the PCI-E. Try re-seating the card in the slot, see if any of that works. If not, let me know

Sadly this came with a few of Nvidia's recent drivers. I am sticking with an older one for now.

Here is a trick to remove it that might work:

This 'Eject GPU' item can be completely removed by going to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm key in the Windows Registry, and setting the SurpriseRemovalSupport value to 0, then rebooting.

I suspect it was the power cables, today I turned on my PC and it told me to plug in my PCI-E Power Cables, so I checked and the 6+2 pin wasn't fully plugged in and loose, I plugged it in and since then, no problems, been running the system for like 6 hours now, will report back if the issue comes back! Thanks for all your help also!
