Internet Explorer Opens In A Blank Page

This is a very annoying problem in which internet explorer (sp1)opens in a blank page.

Cause:-It happens if some dll files are not registered.

Solution:-
You have to re-register the dll files.
Start>Run>regsvr32 urlmon.dll>ok
Start>Run>regsvr32 actxprxy.dll >ok


Now again:-


Start>Run>regsvr32 scrrun.dll‏>ok
Start>Run> regsvr32 msxml.dll‏ >ok
Start>Run>regsvr32 shdocvw.dll‏ >ok
Start>Run>regsvr32 browseui.dll >ok
Start>Run>regsvr32 msjava.dll>ok

Now restart your computer and open internet explorer.

But I think best option is to switch over to Service pack 2.
