Question CPU Temperature and Frequency spikes (AMD)

[Frigozzo]

Up until a few days ago my cpu would run normal(38-42 celcius degrees, 3200-3400MHz in idle), but yesterday for some reason it started having spikes in temperature and frequency(40-70 degrees, more than 4400MHz in idle). Now i know it isn't really a big deal, but i really don't like it. Also while trying to fix this. i found out that in the bios, the settings for overclocking where set to auto instead of disabled(i think it's default). and i reset all bios setting. I also tried to reinstall nvidia drivers(as i saw that many people solved by doing this) and i changed the thermal paste, and although the problem is mitigated, it still happens, does anybody know how to fix this? Also because today i think my cpu tempature was detected as over 90 and the pc restarted.

Components:
CPU: Ryzen 9 5900x
GPU: GTX 970 Windforce trio
MotherBoard: Rog Strix x570-E Gaming
PSU: Corsair RM850
Cooler: NZXT Kraken x53

One thing. CPU and BIOS don't do anything by themselves and BOS doesn't change any settings on it's own. operating system decides what to ask of a CPU. (GPU and other parts as well).
So if you get sudden spikes in CPU and other's usage , it's because there's something running in the background.

Yeah i know, i'm just stating the fact that overclock was set to enabled in bios(instead of auto, which is default setting, i checked earlier), when i never changed the setting. Also there isn't anything in background that would require that much power, from what i saw, unless the antivirus counts but i doubt it requires that much
