[求助]Faulting application dexplore.exe

[Henern]

去年装的VS2005 + MSDN，一直用得很好。
最近MSDN老出问题，通过索引随便查几个C#的帮助就出错，以下是事件日志的内容：

Faulting application dexplore.exe, version 8.0.50727.42, stamp 4333d0b3, faulting module msvcrt.dll, version 7.0.2600.2180, stamp 4110962b, debug? 0, fault address 0x00037fd4.

感觉错误发生完全是随机的，同一个帮助内容，这次点没问题，下次可能就出错。

微软的论坛上好像有不少人也碰到类似问题，但似乎没解决。
抓狂了，高手帮帮忙。。。。。
