Hello everyone, I just built my new rig but unfortunately I'm experiencing while gaming sudden fps drop and freeze of about 1 second every 30 sec-1 min.
Yesterday while playing Fifa I had a big freeze and the PC rebooted autonomously (No BSOD).

Could you give me an help to solve this problem or at least identify the causes?

Here the configuration:

-CPU: AMD Ryzen 7 3700x
-GPU: Gigabyte RTX 2070 Super Windforce
-MOBO: MSI B450 Gaming plus max
-RAM: Patriot Viper 4 3733 MHz
-PSU: Corsair TX650M

I tried to deactivate the Windows Game Mode and the DVR function through system registry but the issue was not solved.

In the attachements you can find the report of HWInfo about my system.
