Update - Exactly one week since I rolled back my GTX 560ti driver to 314.22, and I have not had one single problem since. When I launch Battlefield 4 it throws up a box saying I need to update, that there may be issues because of my older driver, but it plays perfectly.
I was really surprised to see system lockups like the ones I was having, simply because of a driver. Oh well, just glad I got it sorted. Thanks for all the advice!
