I have the same video card and the same problem.  It's called a TDR -- Timeout Detection and Repair.  Your GPU (video card) is freezing, so Windows (Vista and 7) is programmed to reset it.  It happens when you're at the upper end of usage.

Sadly, there is not one fix for this, and I have not found it yet.  I have updated drivers, turned off Aero, turned off all power management schemes, run memory checks, checked to be sure the card wasn't factory overclocked, run a CPU stress test, checked system temperatures...  Nuthin.  Still happens.  Sometimes in photoshop, too, when I'm placing a mammoth layer or using a huge, detailed brush. 

If you manage to find a solution, PLEASE tell me. 

My specs:
Intel i7 quad core 267GHz (no OCing)
12GB RAM
NVIDIA GeForce GTX 260
Win7 x64

Intel Core i7-8700 6-Core 3.2 GHz (4.6 GHz Turbo), 32GB RAM, two GeForce GTX 1080 Ti GPUs

DS 4.10, Photoshop CC and CS6, Poser 11 Pro, Vue 2016, CarraraPro 64bit, Autodesk Inventor, Mudbox, and 3DS Max
