0.3 NEW SEASON TURNS MY PC BLACK SCREEN

It was fine playing through the campaign.
But the game start crushing my pc to black screen after I got into mapping.
For 2 days already, it randomly turn my pc into black. I have to force turn off and restart the pc.
I tried so many different setup (within game setting and pc setting), it now can't even start the game.
the moment I launch GGG's client, it turns into black.

I'm fraid doing so many times force turn off and restart will break my pc, mostly the graphic card.
It must be the game optimization not doing well for this season 0.3 patch.
Please work on game optimization better and provide more hot fix asap.

It's completely unplayble now for me. I supported with $480 the ultimate pack. Please help!!!
