CPU 温度

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，我的电脑会突然重启。我不知道原因是什么，也找不到合适的文章来帮助解决这个问题。接下来，我将解释我的尝试，试图找出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”：

我第一次安装 Ubuntu 时，曾多次尝试让 Nvidia 驱动程序运行，但官方的 nvidia 驱动程序都无法识别我的 nvidia 卡。因此，我目前正在运行 Noveau 驱动程序。

有人能告诉我我的电脑出了什么问题吗？我很感激你的建议！

谢谢！

答案1

CPU 温度

该stress-ng工具显示所有 8 个 CPU 的温度均为 87.0°C 至 92.0°C（接近 200°F）。这些温度会毁坏您的机器。

检查风扇是否正确接线、连接和运行。

检查您的 BIOS 中的自定义风扇设置。

尽快降低温度！

超频

如果您的 CPU 或 RAM 超频，请将其恢复为默认值。

BIOS

华硕 PRIME H310M-E R2.0/BR

您的 BIOS 版本为 1402，日期为 2020 年 5 月 21 日。

有较新的 BIOS 可用，版本 1605，日期为 2020 年 8 月 14 日，可以下载这里。

注意：请确认我拥有适合您主板的正确网页。

注意：更新 BIOS 之前请做好备份。

英伟达

NVIDIA 公司 GK208 [GeForce GT 710]

关于 Nvidia 的问题...当前驱动程序版本为 450.66，可以下载这里。

确认 BIOS 中已禁用安全启动。

清除所有当前的 Nvidia 驱动程序，然后安装新的驱动程序。

在此处输入图片描述

在此处输入图片描述

更新＃1：

您从 Nvidia 驱动程序收到的消息表明 450.66 不支持您的视频卡，因此它们不适用于您的配置。您需要联系 Nvidia 支持部门询问要使用哪个驱动程序。在此之前，请选择 Nouveau 视频驱动程序，然后再次清除所有 Nvidia 内容。

答案2

的输出ps auxc | grep therm是：

root         228  0.0  0.0      0     0 ?        I<   07:39   0:00 acpi_thermal_pm
root         872  0.0  0.0 134500  9892 ?        Ssl  07:40   0:00 thermald

我成功更新了 BIOS 版本并安装了 Nvidia 驱动程序 450，但计算机在安装过程中自行重启。

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

附言：这台电脑很新颖……我两周前买的。
