Ubuntu 20.04 偶尔会突然重启

Question

我在台式电脑 Intel i9 Core 16Gb RAM ASUS 主板上使用 Ubuntu 20.04。有时，当我运行 OBS Studio、Skype、Chrome 等应用程序时，我的计算机会突然重新启动。我不知道其原因，也找不到可以帮助解决此问题的合适文章。接下来我将解释我的尝试，试图找出我的硬件可能存在的问题。

输入后的结果last reboot显示，我之前的 Ubuntu 运行在意外重启后显示为“仍在运行”：

当我第一次安装 Ubuntu 时，我多次尝试让 Nvidia 驱动程序正常工作，但任何官方 nvidia 驱动程序都成功识别我的 nvidia 卡。因此，我目前正在运行 Noveau 驱动程序。

\n

我使用该工具对我的 CPU 进行了压力测试stress-ng，并安装了powertop该工具来检查我的硬件设备的功耗。我的电脑连接到不间断（600 Va），压力测试期间我的硬件最大功耗为104W。根据sensors，压力测试时我的cpu核心温度为：

谁能告诉我我的电脑出了什么问题？我很欣赏这些建议！

Answer 1

CPU温度

\n

该stress-ng工具显示所有 8 个 CPU 的 CPU 温度均为 87.0\xc2\xb0C 至 92.0\xc2\xb0C（几乎为 200\xc2\xb0F）。这些温度会毁掉你的机器。

\n

检查您的风扇是否正确接线、连接和运行。

\n

检查您的 BIOS 中的自定义风扇设置。

\n

尽快降低温度！

\n

超频

\n

如果您的 CPU 或 RAM 已超频，请将其恢复为默认值。

\n

有更新的 BIOS 可用，版本 1605，日期为 2020 年 8 月 14 日，可以在此处下载。

\n

注意：验证我是否拥有适合您主板的正确网页。

\n

注意：更新 BIOS 之前请做好备份。

关于Nvidia的问题...当前的驱动程序版本是450.66，可以在这里下载。

\n

确认 BIOS 中已禁用安全启动。

\n

清除所有当前的 Nvidia 驱动程序，然后安装新驱动程序。

\n

\n

\n

更新#1：

\n

您从 Nvidia 驱动程序返回的消息表明 450.66 不支持您的显卡，因此它们不适用于您的配置。您需要联系 Nvidia 支持以询问要使用哪个驱动程序。在此之前，选择 Nouveau 视频驱动程序，然后再次清除所有 Nvidia 内容。
