我正在使用 Ubuntu 18.04。
我的电脑突然死机了。一切都冻结了，声音卡在“嘘”的响亮声音中。
我想知道这是否与板载声音芯片有关，禁用了它但问题仍然存在。网络控制器也是如此。
我进行了一整夜的内存测试，没有返回任何错误。
我的 google foo 指示我可能会在/var/crash文件夹中找到相关信息，而且事实似乎确实如此，因为时间/日期与最新的崩溃相符。
以下是其内容：

您的 BIOS 版本太旧了，为 2016 年 10 月 19 日发布的 1.F0 版本。
去https://us.msi.com/Motherboard/support/Z170-A-PRO并从 2018-07-16 下载并安装其更新的 BIOS 版本 7971v1K。
