Crash during Conversations/War Room

Firstly here's my DxDiage info: http://pastebin.com/vCpnvpyn

I've been trying all the solutions I can find on these forums and others but no luck with any of them. Basically whilst I'm playing during conversational pieces and now whilst in the War Room the game will literally just lock my pc up and it seems like my display just shuts down (I get 'No Signal' on my monitors). It seemed random at first but now it's actually hindering my progress in the game, every time I try to advance a particular mission in the War Room it happens.

I've checked the temperature of my GPU whilst playing and it never exceeds 80C. I've tried it on the whole spectrum of settings, diabling SSAO/HBAO etc. Disabling Origin overlay, disconnecting from dragonagekeep and offline mode in Origin, running in compatability mode and as administrator, reinstalling the game. You name it, I've probably tried it.

I'm not really aiming for a solution here (but it would be nice!) but I just want to know if anyone else is suffering with this particular issue and to just hopefully let someone up above maybe know about this issue.

EDIT:Just wanted to clarify that the crash results in me having to hard reset the machine.
