Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems BG3 shutting down PC entirely

For those impacted using an AMD CPU: worth checking that your graphic card is using a PCIe slot connected directly to the CPU and not one connected to the motherboard chipset. Generally, it means checking that your graphic card is in the topmost PCIe slot of your motherboard. Also, it may be worth testing with every other PCIe devices removed (if any) (NVMe drives using the topmost slot should also be fine).

I have encountered instability issues with how some AMD motherboard chipsets handle high load. Strongly doubt that this is what's happening for most people here though, but who knows.

Edit: also, I think someone else already mentioned it in this thread, but maybe trying to update the motherboard BIOS ? I'm bit reluctant to recommend it, given that it's a bit of a crapshoot whether it will actually help or make things worse.

For owner of AMD GPU cards, I have heard that updating the GPU BIOS can help. Never tried it myself though, and it doesn't seem to be officially supported by the manufacturers. Feels like a bit of high-risk procedure.
