Last night my system died while I was playing Arkham Origins. I've had the 980ti SC Acx2 for about 2 weeks now (built a new skylake system).
After post the card just shows a grid of red dots then a black screen. Sometimes after about 5 mins windows will bluescreen with video_tdr_error. After this happened and because I couldn't get Windows to start, I reinstalled windows, which goes fine until you install the nvidia driver and reboot; then I just get the same thing, red artefacts then black screen. I can get into safe mode but I've now tried 2 drivers and 2 windows installations with the same results.
With another monitor via DVI, the system behaves the same way, black screen after post, possibly followed by video_tdr_failure, but via DVI the red spots are always there, during post and when running safe mode or UEFI
I've removed the card and connected displayport to on board graphics and that works OK.
Any suggestions? Could it be that the card suffered permanent heat damage?
