13600kf crashes without load

[SergeyS18]

Hello,
 
Can you help me solve a problem with my i5 13600kf processor, please.
This processor was purchased in November 2022. It worked fine for a year, but then (approximately in December 2023), the PC started completely freezes without load.
 
 
PC Specifications:
BIOS ver. – 1820
Windows 10 – 22Н2
 
Hardware:
Gen Intel(R) Core(TM) i5-13600KF   3.50 GHz
Asus PRIME Z790M-Plus
RAM Kingston Fury Beast Black AMD [KF556C36BBEK2-32] 32 ГБ
SSD Samsung SSD 980 1TB, SSD Samsung SSD 980 PRO 1TB
NVIDIA GeForce RTX 4080 (16 GB)
ATX Be quiet! System Power 10 850W
 
 
The following steps were taken:
1. The BIOS was updated and Windows was reinstalled.
2. PC components were replaced (motherboard, graphics card, power supply, RAM).
 
Considering that the PC was running smoothly under minimal load, my brother wrote a simple program that counted from 1 to 100.
 
Program code:
@Echo off
 
SET A=0
:rep
SET /A A=%A%+1
title " Loop %A% "
for /L %%c in (1,1,100) do (
  echo %%c
)
goto :rep
 
 
 
With this program, the PC ran well, but if it was shut down (during Windows shutdown), it could completely freeze at any time. Also, completely freezes occurred during Windows boot (20-30% of cases). After one reboot, Windows usually loaded and I could run the program.
 
Recently, freezes during startup have become more frequent, and now it takes 10-15 reboots to even get to the program startup stage.
 
Also, computer does not freeze in BIOS.
 
I think the issue is related to processor voltage surges during working without load.
 
Can you recommend any changes to the BIOS settings to stabilize the PC?
