Warzone / W10 / Possible DirectX issue

Been running Warzone / Modern Warfare since launch on a HP Laptop W10 and 4Mb Nvidia card without any issues. One week ago the problems started - mid game, the PC would show a blue screen briefly, (Saying Locked screen) and PC shut down.

Have tried the following

  1. Updated graphics drivers
  2. Ran update and repair (only worked when windows defender and avast disabled)
  3. uninstalled and reinstalled game from scratch.

One of the error codes that came up on the blizzard repair run mentioned a DirectX12 issue. This is also fully up to date.

I’m a bit stuffed.

Any thoughts??

****** FIXED - reverted back to DirectX11 and no issues *******
