X870 Gaming Plus WIFI Freezes

hi I have a MSI X870 Gaming Plus WIFI motherboard with ryzen 7 9700X and 2 x16 GB Corsair Vengeance RAM set to minimum at 4800Mhz and every now and then everything freezes and I have to force restart to unblock everything. It does it in idle, when I switch from one window to another, when I want to install Windows while writing to SSD, NVME or SATA, with or without GPU installed, rarely in Gaming. I've tried everything. Faulty motherboard? The BIOS is updated to the latest released on March 24th.
