Amazing, i came here looking for exactly this issue, I didn't think I would find anything, but here we are.
I have the same problem, BSOD in battlegrounds. Tends to happen when I die on the death recap screen.
Happened just recently in a great winning match, managed to get back in game quite quickly but only to discover I had the leavers penalty, quite annoying.
My system is very stable, everything updated, hardware in good shape, never normally get BSOD, only happens during battlegrounds in this game.
Please look into it ZOS.
