Question Weird problem with current setup

[manytools]

Hi guys, recently upgraded to Am5 platform but unfortunately there is a major problem. Whenever i do slight changes in bios (sometimes even just enter and leave) pc starts to stutter, mouse freezes for seconds, weird crashes happens aswell but no Bsod. But when i repair Windows with builtin "Reinstall Windows Update" thingy it solves all those issues.
Did a research about this but could not find anything. Any help would be appreciated.

Os: Win. 11
Mobo: B650 Gaming Plus Wifi (downgraded bios to 7E26v1G from latest beta version)
Cpu: 9700x (Stock)
Ram: Patriot PVV532G600C30K (Expo Profile 6000Mhz. Cl30)

Yes, Windows was freshly installed at the first place.
Did not run any stress tests yet but played PoE 2 and EFT for hours but cpu did not reach 85.
Cpu cooler is NH U14s with Akasa Viper 14cm
Case is H510 Flow, 2 Akasa Viper 14cms on the front, 1 slim model of the same fan on top and 1 Akasa Viper 12cm at back.
