近来玩游戏时出现机器突然变慢的情况，用瑞星、ewdio在安全模式下杀毒会死机，然后发现cpu风扇出问题导致cpu温度过高，十分烫手，换风扇后温度降下来，但机器依然不正常，昨天中午重装后没有连上网络，直接装暴风影音，还是慢的连普通的影音文件都很卡，但有时、有些程序却似乎正常，表现为：
1。开机进入系统时在蓝色欢迎画面停留的时间较长，进入后瑞星监控长时间后才启动，任务栏长时间无法显示。此时在任务管理器中，taskmgr、explorer占用大量cpu。
2。大约20秒左右恢复正常，cpu使用率降至2%，若保持空闲则维持2%-4%，但一旦开启诸如瑞星，千千静听，暴风影音等程序后升至100%，taskmgr与explorer占用大量cpu，特别是taskmgr，在30-50，有时70以上甚至更高。但如果关掉这些程序，又恢复正常。另外，开IE或遨游上网却没事。有时ravmond也大量占用cpu且延续大约1秒。
3。昨晚曾卸载千千静听后重装，再放，正常，今天又不行了。
4。安全模式下，刚一进去，在任务管理器中taskmgr占用大量cpu，10秒后正常，空闲时正常，鼠标移动时正常，若用鼠标拖拽任务管理器移动，taskmgr迅速升至70以上，要大概3秒左右才恢复。安全模式下开瑞星，启动超慢，杀毒也慢，一个小时大概查4万个文件。

我已经上网查过不少，启动项已经优化过，机器配置，赛扬2.4g，msi 845pe 主板，512m内存，三星80g硬盘，msi mx4000显卡。
另，会不会由于硬件问题造成？如电源不行，cpu问题，主板问题等？但是如果是硬件问题，为什么空闲时，使用ie，遨游等正常？

下附sre报告，如果有问题请指出，如果各位高人看不出什么问题，也请留个话，那就可能是硬件问题了。

硬件问题也有可能。

不过还是扫个SRENG日志先看看系统有没有好玩的东西。
