我的电脑出现了一个不寻常的问题。每次我重新启动电脑时，电脑都无法启动，BIOS 会发出几声哔哔声，除此之外什么都没有，但是如果我等几分钟，电脑就会完美启动。
我试着数了数哔声，大概有 7-9 声；前两声明显比其他两声间隔更近。[编辑：我现在相当确信它是 1 声长哔声，然后是 8 声短哔声。那可能是与显示相关的问题：http://www.bioscentral.com/beepcodes/amibeep.htm]
我的 BIOS 是 American Megatrends Inc，版本为 P1.80，主板是 ASRock X58 Extreme（均根据 dmidecode）
这是来自 LSPCI 的输出，我不确定还有什么可能有用，但我可以提供任何要求的内容。

答案1
检查温度。我的电脑运行温度过高，这并没有导致电脑崩溃（尽管它降低了 CPU 的速度），但重启会失败，因为 BIOS 不允许电脑在如此高的温度下启动。
这与您的问题在几分钟后当组件（最有可能是 CPU）冷却下来时消失的情况一致。
对我来说，解决方案是：安装一个额外的风扇。
临时详细信息公布后的更新：核心温度 60°C 绝对不算低。127°C 的标记temp3很可能只是传感器错误。
CPU 温度达到 60°C 很可能是 BIOS 的抱怨。如果您的 CPU 风扇运转正常，高温可能是由机箱内空气循环不良引起的。尝试安装额外的机箱风扇。
首先，最好得出结论，温度确实是问题所在。运行没有底盘侧板的计算机，并用显示器sensors查看 CPU 温度是否降至约 40°C。然后尝试重新启动。如果可以，则很可能与温度有关。
如果温度一直降不下来，可能是你的 CPU 风扇被灰尘堵塞了。谷歌搜索清洁方法，看看效率是否提高。
