我有一段时间遇到这个问题了。在玩某些游戏（不是特别费力的游戏）时，我的电脑会随机重启。
对我来说，似乎 GPU 以某种方式关闭了...我不知道。
有些游戏运行完美。例如，我玩 GTA 5 玩了很多个小时，没有出现过一次崩溃或延迟。而有些对硬件来说并不“困难”的游戏，如 Stronghold: Warlords，经常会导致崩溃，然后系统重启。
我尝试在网上查找类似的问题，但我不明白的是，GTA 5 和巫师 3 对硬件的要求比 Stronghold（例如）更高，但第三款游戏却导致崩溃。
总是一样，过一段时间后就会重新启动。在那个屏幕上，计算机不响应任何命令。
我认为这可能与 GPU 驱动程序有关......
