I am not sure why...

Each time i try opening it, with either hitting a link, or opeiing up the program i get his error, and it shuts down
IEXPLORE casued an Invalid page fault in
module MSXML.DLL at 0167:71205bf1.
blah blah blah yadda yadda yadda

I can use Windows Exploer, or my ISP browers (which seems slower) but once i hit a link to open up a new browser page IE fired up and dies. Sometimes my computer might lock up for a few minutes.

any help is appricaited, to either fix it, or curcumvent it
