I recently completed a build about 2 weeks ago. I've been having fun playing BF4 and such, but lately I've noticed it's starting to get lower fps than usual and stuff is running a bit slower. I have a EVGA GTX 760, I5-4670K, Asus Z87-A Motherboard and 8gb of RAM. Just wondering if there is anything I can do to see what could be causing the problem?
