我正在运行一个相当老版本的 CentOS 5 开发服务器。这台服务器在过去五年里几乎一直处于运行状态，因此一直很稳定。不久前，它在正常运行期间崩溃了。我重新启动它，几个小时后它又崩溃了。主板加载屏幕抱怨 CPU 过热。我打开盒子清理灰尘，确实发现一大团灰尘堵塞了 CPU 上的散热器。我还更换了 RAM，不幸的是，RAM 在此过程中受到了一些物理损坏。
服务器继续崩溃，但时间不同：
- 在操作系统启动初期，就在 GRUB 屏幕之后。
- 每次我登录并尝试启动 GUI 时，它都会立即崩溃。
- 如果我不启动 GUI，我可以使用 SSH 连接并使用服务器。它通常会在几个小时后崩溃。
- 如果我运行 yum 更新，它似乎很快就会崩溃。
我通过以下几个方面进行了调查：
中央处理器 据我所知，崩溃似乎与高服务器负载无关。我一直运行 top 直到它崩溃，当它冻结时，服务器负载似乎很低。
内存 我运行了 memtest86+ 近 9 个小时，它显示 RAM 正常。
硬盘 我对这两个驱动器（它们位于 RAID 1 阵列中）运行了坏块测试。报告显示两个驱动器都完全正常。
操作系统 GRUB 让我从 4 个内核中进行选择。我尝试了其中一种方案，但没有什么不同。
日志 我没有查看 Linux 日志的经验。我在下面发布了两个来自 dmesg 的输出，每个输出都来自崩溃和重新启动之后。日志中的某些消息可能与 USB 设备有关：有一个 KVM 交换机导致键盘和鼠标定期连接和断开连接。
所以... 我认为我需要重新安装 CentOS（我可以升级到较新的版本），并且这与硬件无关。不过，我很乐意听取其他人的意见。

你遇到了以下错误：
hdc：LITE-ON DVDRW SOHW-832S，ATAPI CD/DVD-ROM 驱动器
我很想删除它，然后重新启动，看看会发生什么。你不是从 LiveCD 运行这个的吧？
不管怎样...切断该驱动器的电源，重新启动，看看会发生什么。此外，也许可以查看 smartctl 以查看硬盘驱动器是否有任何 SMART 错误。
