First, we need to get a little organized, this is not something I do a lot (troubleshoot) and I need to get feedback from things I suggest so I will know what I have tired.
I asked you to run System File Checker, was this done and did it help?
Have a look here: http://forums.techguy.org/windows-nt-2000-xp/638168-problems-internet-explorer.html
the first message posted is:
szAppName : iexplore.exe szAppVer : 7.0.6000.16512 szModName : hungapp
szModVer : 0.0.0.0 offset : 00000000
which is exactly the message you posted. Read the suggestions in this topic, it may be a broswer issue.
Let me know about System File Checker And what happens when you try the suggestions in that link.
My next question, do you have another browser besides Internet Explorer?
Thanks
