Random FPS drop due to CPU and GPU in all games

Hello everyone!

After a period of time (maybe 4 months) I come back to my desktop pc, I had lots of updates and I did all the drivers updates as well.

But when I began to play games I noticed that I have some random FPS drop in almost all games, while month ago they worked perfectly, with 30 to 60 fps. Now they go from 60 (or 30) to 20 or 10 fps, randomly!

I figured that the problem is that CPU and GPU are dropping for ~10 seconds, and then start working well again for another ~10 seconds. Like this.

I already tried to do some stuff I red online, like disabling "Cool 'n quiet" from bios, or disabling the xbox's GameDVR, but nothing changed.

Please help!

My PC stats (I know they are not the best, but games like GTA V, or The Witcher 3 worked perfectly before).
Windows 10 Pro (Updated to 1709)
CPU: AMD FX-6300 6 core 3.52 GHz
Mainboard: ASRock N68C-GS4 FX
RAM: DDR3 8GB
GPU: AMD Radeon R9 270 (975 GHz) 2 GB

Thank you in advance!

I thought that temperatures may be the problem, but they do not exceed ~60° while ingame.

Ok I fixed it.
Somehow the CPUIN temperature (of the motherboard) started rising over 83°C (180F) and the CPU speed become slower to cool down the temperature.
But the CPU Core temperature was actually fine, around 63° C. Online I red that this may be a problem of a motherboard's diode (?) that reads the temperature wrongly.
So I decided to ignore the motherboard and deactivate CPU Thermal Throttle in the BIOS, and now it goes fine.
