无法打开系统chm

我xp中的系统chm，如secedit.chm, winime.chm等等windows\help\下的绝大多数chm一打开就死机，cpu占用100%，光hh.exe内存占用有170m， 5``````但我自己下载的其他chm却能正常打开。
我个人觉得是不是系统里禁用了什么服务或其他的，有人和我有过同样遭遇的吗，帮帮我呀~~万分感谢，给点思路也好~~！
在这里先谢大家乐~~

下面是打开secedit.chm时，hh.exe运行时调的dll文件
hh.exe ntdll.dll, kernel32.dll, msvcrt.dll,
ADVAPI32.dll, RPCRT4.dll, USER32.dll,
GDI32.dll, ShimEng.dll, AcGenral.DLL,
WINMM.dll, ole32.dll, OLEAUT32.dll,
MSACM32.dll, VERSION.dll, SHELL32.dll,
SHLWAPI.dll, USERENV.dll, UxTheme.dll,
IMM32.DLL, LPK.DLL, USP10.dll, comctl32.dll,
comctl32.dll, hhctrl.ocx, hhctrlui.dll,
MSCTF.dll, NTMARTA.DLL, WLDAP32.dll,
SAMLIB.dll, CLBCATQ.DLL, COMRes.dll,
itss.dll, urlmon.dll, WININET.dll,
CRYPT32.dll, MSASN1.dll, msctfime.ime,
shdocvw.dll, CRYPTUI.dll, WINTRUST.dll,
IMAGEHLP.dll, NETAPI32.dll, Secur32.dll,
SXS.DLL, shdoclc.dll, xpsp2res.dll,
Mshtml.dll, msls31.dll, PSAPI.DLL,
mlang.dll, pdm.dll, msdbg.dll, msimtf.dll,
jscript.dll, msxml3.dll, MSOXMLMF.DLL,
SETUPAPI.dll, appHelp.dll, HelpCtr.exe
好像比其它正常的xp运行自带的secedit.chm时少了些，希望有帮助````
