Player motion can't be stopped, system needs hard reboot

At various times and duration of game play, Henrys movement is unstoppable, even on a horse. I can control his direction with mouse, but no other input from keyboard or mouse works which requires me to shut down system. This has happened infrequently with previous patches, but has caused me to reboot every time I’ve played KCD in the last few days. Playing KCD is the only title this occurs, not even my flight sims give me issues which are CPU heavy. System specs- DxDiag.txt (37.3 KB)
