Black screen crashes

[dma550]

Hey all

Sometimes while playing my screen goes black and I cannot control it, it seems like a soft lockup. (not a blinding mob) I still hear music and other things but am locked out of my character. This is maybe the 5th time I have died while this happens. I have to kill the task and when I return no matter how full of health or "winning" I was I am dead. It seems I am going into a LD state. I though when LD your character tries to survive? In this case my character had 80% HP and the hill giant maybe 10% and was fleeing. Very frustrating!
