I may have a workaround. After doing a *lot* of web scouring I have found something that has worked for me so far. I am still using the 359.00 drivers, which crashed twice in 24 hours before.

I've read that overlays might cause this issue. Three specifically mentioned were Fraps, MSI Afterburner and the NVidia Experience. I don't run Fraps while I'm playing most of the time, but I did have the other two apps. I uninstalled MSI Afterburner and Nvidia Experience. I've now gone a few days (and a lot of dungeons) and have yet to crash. Note that I do have Steam installed, so it doesn't look like the Steam overlay is an issue. I'll continue to test. If this works I'll install the latest driver, remove NVidia Experience, and give that a try.

Hope this helps.
