[SOLVED] CPU Usage drops

[gskk]

Hi, recently ive been experiencing some CPU usage drops causing fps drops in some games (usually in large areas). The weird thing is the CPU usage doesnt always drop. As seen here

the CPU usage went back to normal literally as I alt tabbed back after taking the screenshot.
Things i tried:
-Reinstalled windows
-Updated drivers
-Switched RAM slots (yes ive read someone having a similar problem and he solved doing this lol)
-Playing the game on SSD or HDD

CPU: Ryzen 5 3500
GPU: GTX 1050
16GB 2666MHz
B450M Steel Legend
