Hi Gerry,

thanks to the fast response.

Here're the requested logs. Please excuse the MSinfo being in German language. I already switched my OS language to English, which worked for the event viewer and speccy, but MsInfo remained in German. No idea why :L

Also I'm using google drive, but I guess that isn't a problem

Update the NVIDIA GeForce GTX 1070 graphics driver to version 378.66

http://www.nvidia.com/content/DriverDownload-March2009/confirmation.php?url=/Windows/378.66/378.66-desktop-win10-64bit-international-whql.exe&lang=us&type=GeForce

Hi Gerry,

I previously had 378.66 installed and switched back to an older driver by intent for testing purposes. It did not resolve my problem though. Will update to the latest anyway for being on the safe side

Have you overclocked your GPU or CPU? If not, maybe your VRMs are failing, as they supply power. Or, maybe your card's thermal paste is failing, as higher temperatures can, in some cases, increase power draw. Last but not least, try dusting your PC out. I've heard that dust can cause issues.

Hi David,

No, I have never overclocked my Cpu or Gpu. My old Intel Xeon is insanely powerful and I haven't met any program or game yet that would have required that and the Gtx 1070 is currently the sixth strongest Gpu on the market. I don't see any reason to tune it besides the fact that I've just bought it last Monday :)

Regarding the thermal paste on the Cpu, everything's fine. I've personally removed the original TP-sticker and replaced it by high quality paste, which covers the whole back of the Xeon and not just the center. The very low temperatures, even on load, speak for themselves.
I can't tell about the TP used on the GTX because you can't remove the massive body and fans that easy and I do believe I'd lose my warranty if I do so. Also the temperatures are perfectly ok during load. I stressed it with Grand theft auto 5 on maximum settings and the Gpu reached only a maximum of 70°C

The insides of my PC are also very well dusted out. I cleaned it thoroughly with compressed-air-spray when building in the GTX and the new PSU

FWIW I cannot understand this report.

It seem to be something wanted from Nvidia, perhaps audio related?

Hi Gerry,

I used the Program DDU (Display Driver Uninstaller) for removing any AMD drivers whilst my old Gpu was still running. Then I shut down the PC, changed Graphics, booted, downloaded the latest GTX driver from nVidia site and installed it.
Afterwards I also did a clean up + registry cleanup with Ccleaner.

That "amdkmdap" is referring to my old AMD Radeon HD 7870. You see there aren't any more entrys past 20.Feb.2017, the date I bought and installed the GTX 1070.

My onboard Audio is from Realtek afaik. Nvidia has installed audio drivers for HDMI but I'm not using the HDMI audio, because it will play back the sound on the TV speakers - what I do not want.
My Audio is running through my onboard soundcard via stereo jack right into my hifi-amp

I read in a similar thread about Kernel-Power errors, that it got resolved by changing the power strip. 
Actually that didn't do it for me. Just tested with a new power strip and the PC still shut down
