B550 Steel Legend - Random Freezing

Good morning everyone

I've recently bought a B550 Steel Legend, but I've facing with two problems:

My PC just randomly freeze without showing a single BSOD message.
Sometimes before it freezes the internet connection (via ethernet) just stop and inmediatly freeze.


This is what I've tried:
-> Clean install of Windows10 and Windows 11 (In Windows 11 setup-screen, it freezed too, fixed it when I unplugged the ethernet cable)
-> Install Video drivers recommended from Windows Update
-> Install video drivers from AMD
-> execute "Verifier" and nothing show up.
-> Use just one stick of RAM
-> Disabling XMP when two rams are in use.




The second problem is:

When my PC is suspending itself or by myself, it just shut down. That happened randomly

My PC components are:
MoBo: B550 Steel Legend
CPU: AMD Ryzen 5 3400g (According to Asrock website, it's officially supported)
PSU: Cylon 500W
RAM: 16 GB of ram (8 x 2) Model: XPG gammix d30 with XMP enabled

Thank you.
