Strange issues over here. I had another BSOD last night apparently, so I turned my system off as I planned to reinstall Windows this morning. So, I go to my computer this morning and... nothing. It turns on, but black screen, and neither video card fan is spinning. Tried each card one at a time, nothing. Tried onboard graphics (not sure if it was ever actually enabled or not, I tried clearing CMOS, but it looks like CMOS never actually cleared), nothing. Tried my old 660 Ti... it boots. Tried one GTX1070, it boots. Tried both, it boots. Fired up Nicehash, crash to black screen in 5 seconds. Reboot, fire up Nicehash again, running fine so far.
I'm thinking power supply issue... but that doesn't explain why my computer wouldn't even start up this morning. It would explain crashes to me, but not why it wouldn't even start up. I did accidentally run the video memory at +600 for a moderate period of time (8 hours or so), but it ran fine that whole time and I've since reset it, as soon as I realized it was doing that.
Ugh, reinstalled Windows and now I'm seeing the miner (sometimes, not always) crash immediately upon startup. Fans locked at 100%, sometimes the desktop comes back, sometimes black screen.
