My pc has a i5 6400 paired with a b250 bazooka and 8gb of 2800mhz (although it only runs at like 2133mhz) trident z ram. My rig is about 2 years old and I've been experiencing for about 1.5 of those years frame drops and freezes when playing games to the point I have to close all windows except the game and in some circumstances it still happens. I've always assumed it's my cpu that is the problem, as I've opened cpu-z while gaming and seen my cpu at 100% but now I'm starting to wonder wether my 8gbs of ram is my problem. I have no clue how to find out what the problem is and was wondering if anyone could help me to find out. Is there any sorts of benchmarks or software that will help me to see?
