So I've been having this problem for about a week now. When I load into an online match in siege, about 5 minutes in my pc resets, doesn't shut down, but resets. This happens in no other game, and I play much more demanding games other than siege and I have no problem. My pc is a Ryzen 7 5800x on an ASUS TUF X570 pro with a RTX 3070, an EVGA Supernova GA 750w PSU and 32gb of ram. So I certainly meet the system requirements for siege. I saw another dicussion with another person who had the same problem as me. He fixed it by changing his maxium processor state, https://steamcommunity.com/app/359
