BSOD Starting Arma 3, BCC 116

hello, Damonjay I'll see if I can help. As I am sure you know, your issue is your graphics drivers/card. All of the dump files I looked at are the same.

Code:

 
VIDEO_TDR_FAILURE (116)
Attempt to reset the display driver and recover from timeout failed.
Arguments:
Arg1: fffffa80070e6010, Optional pointer to internal TDR recovery context (TDR_RECOVERY_CONTEXT).
Arg2: fffff88004eaa81c, The pointer into responsible device driver module (e.g. owner tag).
Arg3: ffffffffc000009a, Optional error code (NTSTATUS) of the last failed operation.
Arg4: 0000000000000004, Optional internal context dependent data.

A TDR failure (Timeout Detection and recovery) basically means your graphics drivers crashed but did not recover in time. Windows assumes a hardware failure and shuts down to protect itself. They can be caused by several things, but it is usually the Graphics drivers or the card. This is your current driver

Code:

 nvlddmkm
start             end                 module name
fffff880`04681000 fffff880`0513c000   nvlddmkm T (no symbols)

I would suggest you follow the below tutorial and reinstall the graphics drivers. I would try a previous driver that you found stable. Install the Graphics Driver and PhysX and nothing else.
NVIDIA Drivers - Avoid Problems

Try that and see if it works any better for you.
