今天计算机不停的热死机，上网看CPU负荷的问题，搜到MaxworkItems设置以及445端口开放的问题。

我的电脑内存2.5G，设置Maxworkitems为1024(十进制)是否合适？不行的话是否在设置小点？

关闭了445端口，不知道有否问题？

另外，用netstat -an命令，系统中还有如下的端口打开的，请帮忙看看：

我现在关闭了445端口，使用没什么影响。

Maxworkitems = 1024，这两天还没死过机。

或许问题已经彻底解决了。

还有一个可能就是散热不好，笔记本被摔过。

如果装有管用的防病毒软件、上网死机就和端口没有关系。

如果不上网死机，和端口就更没有关系了。。

楼主还是在系统方面找找原因吧。。
