Question PC Restarts After CPU Upgrade On Certain Games

Dec 26, 2021
So I recently upgraded my CPU from Ryzen 5 3600 to Ryzen 7 5800x and now when I load up certain games my PC restarts. Seems to happen when I actually start playing the game, so I'll load up Rust and once I finally load into a server it'll restart. So far it's happened with rust and Fortnite. But I can play Valorant just fine. Any idea what's causing this?

My specs-
Gpu- 3070
CPU- Ryzen 7 5800x
Psu- Seasonic 750 watt
Mobo- Asus B550 PRO4
Ram- 16gb
Storage- 1tb nvme 2 tb hdd

Also I've monitored the temps and they aren't different from the games I can run and can't run. Never goes above 70 so don't think it's an overheating issue
