New Thread, stop message.

My computer starts up and freezes then just before the desktop icons it would appear and this error message appears on my computer screen "The Ordinal 166 could not be located in the dynamic link library iertutil.dll" There are no icons, only wallpaper and that's about it is nothing else works? This kind of same error message pops up no matter what I click on or try to do.
I also downloaded a new driver from a driver update service for Internet Explorer 8 and Internet Explorer is gone. Also not able to get any kind of utility to work so can't roll back any driver, or make use of system restore...nothing works! I never had anything like this happen before in my computer? The only way I can shut down the Win XP Pro is by pressing the Control-Alt-Delete and click the Shut Off. Can anyone tell me what the wrong is and maybe that how can I fix it without going to the shop?

See if you have inserted the XP installation disk and then use the repair option, reply me if it works on the computer.
