Hello i had same problem just not with titanfall but my problem was high ram usage and that caused BSOD but you got 8gb ram, i had 6gb ram then i upgraded to 8gb ram problem solved. But have you tryed to look under task manager and under performance and looked after it there i can see that the Minimum Requirements for titanfall is 4gb and Recommended is 8gb, But could be high ram usage, hope you fix it!
