For a majority of people having this problem it has been ongoing since the beta. It ONLY happens on this game. That's it. I, as well as many others, can run any other game with zero issues, run hours of stress tests with zero issues, yet this game I can be in the menu screen for 10 minutes and it just shuts off the pc, I can be in a game for 10 minutes and it shuts off the pc, I can be in the queue for 3 minutes and it randomly shuts off the pc. We have tried every different recommendation, yes including updating bios, which I was already on the latest one and between the beta and full game release another bios update, updating chipset, updating ssd firmware, multiple graphics driver updates, using ddu to completely remove previous graphics updates, turning off integrated graphics in bios, turning off XMP for ram, limiting cpu power in bios, underclocking the graphics card, increasing fan curves, limiting cpu in user.cfg, repairing game files, repairing anti-cheat, allowing anti cheat in windows security, trying the game on the ea launcher instead of steam, turning graphics all the way down, limiting fps in game and nvidia control panel, and whatever other random fixes people have tried to come up with.
All of this with a fully custom built non "wallmart" pc. This problem has nothing to do with if you have a prebuilt or not, or if your bios is up to date. At this point I'm 99.9% sure it's the anti cheat. But it is hilarious that you can come in here, read through this thread, then think "yeah it's definitely because you all haven't updated your bios and also since I built my own pc let me make sure to tell them pre builts are also the problem."
