Hi Andrew, is your Screen just frozen or did you have a black screen? I had Black Screen after 10 minutes Asphalt 8. Maybe you should disable IGD Turbomode at BIOS. It made my system More stable (specialy WIN10). Did you make a dirty Upgrade to Mirek ROM V3 or did you cleard everything.
Changed the BIOS settings and did a clean install and still no joy. I managed to disable the animations in Carcassone and it appears to be working without animations. Interestingly I tried Asphalt 8 with full graphics options enabled and had no problems. Must just be some specific software issues.
Thanks Karl and Gammlerlord for the advice
