116 BSOD, even after replacing graphics card and reinstalling drivers

Here's my original thread at MS forums:

Lots of random BSODs, trying to figure out what is going bad - Microsoft Community

There are links to dump files and bluescreenview screenshots there and a description/history of the problem.

Turns out my old GTX 680 did have some issues which were made clear when it crashed during benchmark on my second system (which has no issues otherwise). So I bought a new reference GTX 970 and it ran great on the second system. Now after coming back to the first system, it's still crashing!

Here's the info from the utility in the sticky in this forum:

EDIT: Attached file to this post as well.

Anything in July or after is with the new GTX 970.

I'm beginning to think it either really is a PSU issue (as per original thread, I tested the PSU with a digital voltmeter and it was fine, but I did not test it under load), some freak motherboard issue (but it didn't crash once while using onboard intel graphics), or driver issue (looks like maybe directx?).

I'm waiting to upgrade to Windows 10 to see if the DX12 will end the crashes. My friend had BSOD issues on his new build and upgrading to Win 10 insider preview fixed it. I'm reluctant to upgrade to the insider preview, but if it keeps crashing to the point of being unusable, I might try it, barring better advice obtained here.

Thanks for any help you can provide, this has driven me crazy and I've already spent $350 trying to fix it!

The problem suddenly appeared in May 2015 out of nowhere (system was built/installed in summer of 2011). It is not overclocked anymore, and to be doubly sure, I reset BIOS to defaults today and it still crashed (actually, it just plain shut off!).

System:

Maximus IV Gene-Z Micro-ATX
Core i5 2500k
16gb ram
gtx 970
wd 1tb with 128gb sandisk ssd for intel bios caching (64gb set for caching)
Windows 7 x64
corsair ax750 psu from summer 2011

EDIT: Note, the GTX 970 has not crashed while gaming once. These were all from Windows desktop/Google chrome/VLC/whatever

Can you upload the files directly to the site please. Screenshots and Files - Upload and Post in Seven Forums

I'll get round to this tonight, bear with me please I apologise for the delay.

I've just looked at the logs and there are a couple of important files missing that we use to get the full picture. Could you run the tool again please and upload the resulting .zip file. Don't worry, sometimes this can take two or three times to capture everything.

Still some files missing, give it another try please mate.
