Bad news…
I just had a new freeze… and it was different than previous ones.
In fact, this time just after freezing, computer shutted down and fan ran very fastly.
(HDD (SSD) led was not set on during freeze).
So, I decided to reinstall my Windows.
During previous Windows installation, AHCi wasn’t enabled in the BIOS. During the first boot, I had a blue screen and it was not possible to boot. After research, enabling AHCI allowed to boot correctly.
Maybe my freezes come from this fact (Windows installtion without AHCI enabled)
