I've found a similar thing with ZOTAC Firestorm, which is their version of Afterburner. Once I stop that running, I get no crashes (so far). Leave it running and I can guarentee Witcher 3 will crash and Chrome will go at some point. EDIT - AMD 6300 CPU - 8 Gig RAM - Windows 8.1 - Fully up to date. Firestorm version 2.0.1 using custom fan curve. Nothing else running (I'm a bit anal about things running in the background).
