每当我使用 GPU（2x GTX 970）渲染（Cycles）时，我的电脑最终都会冻结（如果正在播放音乐，发生这种情况时会发出很大的失真声）。然后我将 BIOS 更新为最新版本，它不再出现这种情况，但现在当我玩某些资源密集型游戏时它会重新启动（在这种情况下是 Terminator Resistance，出于某种原因 Doom Eternal 不是问题）。
通常情况下，我会认为这些重启是电源问题，但它的功率真的很大（850W，去年买的）。我的主板很旧（2012 年买的）。这可能是问题所在吗？另一种可能是主 GPU（GTX 970 之一）不好。它们都是二手的。
我最近遇到的另一个问题是，更换 BIOS 电池后，计算机无法使用 PCI-e 插槽中的任何东西启动。升级 BIOS 后，我能够使用两个 GPU 正常启动。
以下是来自 CPU-Z 的一些信息：
