So, lately when I'm playing Mass Effect 3 in certain locations (currently 2 different side mission & ending point) it Blue screens, "page_fault_in_nonpaged_area" it mentions "prl_vadd.dll" as the possible cause. repeats on reload/replay, even when backtracking in game itself. sometumes, though not always sound will stutter, other times cutscene just freezes before bringing up the blue screen. yet the game itself had played fine, without issues before. and still does. not sure if there is anything I could do?
