Ok going by cpuz screen shots
you have ddr3 1600mz ram , you said kingston , timings are 11,11,11 which is a fairly slow module anything over cas 9 is too slow ,
your cas latency determines how fast your ram can communicate with your cpu the larger the number the slower the speed.
I would recommend getting 2 new 4gb sticks with a cas latency lower than 9 .
i can suggest some kits at 1600mhz with cas 7 or cas 8 if you like , where are you from , can give you local price
