I think I'm having similar issues to those posted here. Event viewer is becoming less and less helpful, each time the GPU crashes there are seemingly less errors produced. I at least found a video of what's happening: https://www.youtube.com/watch?v=ZNJNvZ3RtyI
Not my video though. My specs are:
Asus Z97-A mobo
Intel i7 4790k cpu
EVGA/NVIDIA GeForce GTX 1080 gpu
16 GB RAM
1TB SSD
