Dr.Watson’s application errors

Im asking the same question again. Hope to get an answer this time. When I run my pages in the explorer, frequently Dr.Watson’s errors pop up terminating the application. The error message that I get is “An Application error has occured and an application log is being generated. Iexplorer.exe, Exception:access violation(0xc0000005), Address:0x70c8e7a4” I have service pack 6 installed in my pc.
These pages work well without errors in the computers having service pack4 & also works well in win98. what should I do to solve this problem?
