Fps problem

[househome]

My computer's specifications are: gtx 750ti 2gb, core i 5 2nd gen, 8gb ram.
this never ever happened, my game used to run smoothly even at heavy places like lava in Town, but suddenly it gives me less fps in such places(20-30, before it was 60); i have tried reinstalling windows to a previous version, replugged my RAMS but it does not work. I play dying light 1 and it is running just like it used to but black ops 2 does not work like it used to anymore.
thank you!!!

P.S this started to happen when I accidently kicked the crap out of my CPU accidently, but why does the fps problem not happen with dying light 1? (its a heavy game)

Resxt thank you so much, uninstalling the game fixed it or because i changed slots of RAM
