IE6 the memory could not be read error

Hi,
I had a problem with my internet browsing. My internet explorer will sometime get confused on a certain link on a web page. I am using Microsoft Internet Explorer version 6 as my browser. When I go across a site, and there is a link, when I click on the link an error will pop-up that tells me The instruction at “0x044d2bf2” referenced memory at “0x04576ae8”. The memory Could not be “read”.
iexplore.exe – Application Error
The instruction at “0x044d2bf2” referenced memory at “0x04576ae8”. The memory Could not be “read”.
Click on OK to terminate the program
OK
But there are also times this link will run. I asked a friend of mine, if he could get into that link, fortunately he can click on the link and load the page, so therefore it's not with the site that hampers me from getting in that link. I suspect there is something wrong with my internet explorer browser.
Please help me solve this link issue.
