Installed a new CPU (Ryzen 7 5800X3D) and now at random times the PC restarts.

Replaced my old cpu with the new one. Before doing so I updated the mobo (B450M/ac) bios to 3.10 as that would support the new chip. Everything started up fine. Ran a round of Tarkov just to see the results, temps seemed fine and have zero issues. Then later in the day the PC just started randomly restarting. Seemed to happen pretty often when I was download BF6 on steam(idk if that helps). I’m kinda new to all this so any help would be awesome!
