这种情况现在比过去更常见。我主要发现，当我观看 YouTube 或 Facebook 上的视频时，我的电脑速度会急剧下降。
我不得不说，这种情况大多发生在我用 Chrome 和 Firefox 浏览器观看视频时。一旦速度变慢，我似乎唯一能恢复的方法就是重启机器。即使我关闭浏览器并运行 bleach-bit 清除缓存等，电脑仍然很慢。
我尝试断开互联网连接，但问题并没有解决。
我尝试重新启动（成功），但是，这也不能解决问题。
系统监视器没有显示任何异常运行，甚至注销然后重新登录似乎也无法解决问题。我一重新启动，系统就运行得和以前一样顺畅。
当我登录 YouTube 并观看几个视频时，计算机就开始运行得非常慢，直到我重新启动才能恢复。
任何建议都会有帮助。
