我有一台 Hp DV6-3079tx。
它有一个 ATI Radeon 图形芯片。
系统似乎会随机冻结，有时会解冻，有时会解冻、冻结，然后变黑。
看看完整日志附有此摘录。

看起来我的图形芯片出现了一些问题。
谁能告诉我发生了什么事？
答案1
使用 LiveCD 重新启动并选择内存检查选项，在运行密集型工作时还要检查 GPU 温度。
答案2
您可以尝试不同版本的 Ubuntu...您正在运行哪个版本的 Ubuntu？
我有一块相当老的显卡，而且似乎只有一套好的驱动程序可以在 Ubuntu 8.04 或类似的非常老的版本中工作。诚然，我还没有深入研究这个问题，看看是否有修复方法可以让它们在当前版本中工作，但目前我正在运行最新的 Ubuntu，显卡质量较差，因为我使用的是它的默认驱动程序。
另外，不要忘记检查内存和 GPU 温度，正如 juancarlospaco 所建议的。这可能表示硬件故障/失灵。
