我有一台 Macbook Pro，购买于一年多前，没有延长保修。
最近它开始出现以下崩溃 - 屏幕变黑。音乐（如果正在播放、广播或 iTunes）的最后一个音符会反复循环。屏幕关闭时它不会进入待机状态。电源按钮不会关闭它，除非按住四秒钟。
上周这种情况开始频繁发生（一天发生几次），所以我从 Snow Leopard 更新到了 Lion。但一点帮助都没有。
我尝试卸载任何第三方首选项窗格（内存管理器、finderpop）。从系统首选项 -> 用户关闭所有登录程序。
今天我尝试从 App Store 安装 Xcode 4。我点击下一步，结果电脑崩溃了。
重启，关闭所有正在运行的程序（据我所知，但我不是专业人士），再试一次。电脑崩溃了。重启，卸载 Xcode 3，正常关机。拔掉电源插头，按住电源按钮十秒钟。重启。再试一次。砰。
所以，我终于找到了一个一致的方法来查找问题，但这是一个严重的问题。拜托，拜托，有人能帮我找出是什么导致笔记本电脑如此不稳定吗？
在 Mac 论坛或其他地方找不到任何有用的东西。根本没理由购买新笔记本电脑。
以下是上次启动时的错误报告。我注意到 panic 计数很高。
