So, for a long time, I've had no problem playing BF3. I took a break for a few months, and when I went back to playing it last month, it would freeze my whole system after 15-30 minutes of playing. The freeze would just be an entire freeze of my whole computer, sound loop, and all I can do is hard reset. I've looked all over for solutions, but everything I've tried hasn't helped. I've got three monitors, but I only use one when I'm playing Battlefield. Any help is appreciated, thanks.
