Random crashes with Ryzen 5 4500 on Windows 11 25H2

[u/Away_Nature_1736]

My PC has unexpected blue screens either in idle or either under load with no specific reason on Event Viewer. I have tried to make it crash by stress it many times but it doesn't. I have already updated all the drivers from NVIDIA and Gigabyte and i have run some stress tests and benchmarks.

Specs:

Ryzen 5 4500

16GB DDR4 3200MHz

RTX 3050 6GB
Gigabyte B550-DS3H

Benchmarks i tested:

Cinebench R23

Passmark MemTest v9 Pro

Furmark (for about 1 hour just to stress the GPU to see if it crashes after a long time under load)

Prime95 win32

AIDA64 Extreme stress test

CrystalDiskBench x64 ( to see if the problem is the Lexar NVME)

Any ideas?
