I usually don't, I just had misclicked the install on the latest drivers, I usually have never installed the 3d stuff, but I had installed the audio before, having often plugged the cards into my home theater or other TV's, I understood that they were required for sound through the HDMI cable to the TV. Like I said I had just let nvidia do an express install on the last update.
I did everything above I said I would try, reinstalled vid drivers, didn't install sound this time (or 3d as usual), cancelled my overclocks on both CPU and GPU, removed the eVGA precision vid card tweak program. I even moved AH back to my spinner drive, as I had recently put it back on an SSD just to see how it worked.
Now in AH I'm getting these flashes of other programs or perhaps the desktop, it's almost impossible to perceive, but it's happening, in like less than a eyeblink, stuff pops into the terrain/screen being drawn by AH in game. Again, I have various monitoring programs running, CPU and GPU temps are way, way below normal, as I have umpteen fans and closed liquid on the CPU, I'm certain it isn't a heat issue, I played for an hour, and checked the logs for hardware resource monitor, and nothing is at all hot, just the reverse. I'm getting 143 fps pegged almost the entire time, no performance drops at all, and I haven't had the original blackout/crash problem happen again yet, but now I'm having that flashing of odd stuff happening. It's doing this despite many changes I've tried in nVidia settings, Gsync on and off, Vsync on and off - it does it regardless of what I've tried fiddling with.
Maybe I got a bad card. The missus is going to yelling later today when she gets a surprise when I steal hers and swap mine into her system - haha. AH is far up the totem poll from stupid WoW and whatever she's playing right now.
Anyone think this could be TrackIR related? Nothing has changed, at all, on that end for me, I've not changed or touched that program or settings in months, so I doubt it, but just trying to rule everything out before I start getting drastic.
