I went to the windows update site to check to see if there were any new updates, it said something about having to download a new version of the update software or something like that. It did that and completed. But now, when I try to run the update again (I get to the point where I can choose between express and custom) when I click on one of the choices the computer audibly clicks and restarts instantly. Has anyone heard of this before? I am thinking if I could just physically delete or reinstall the updater program (which I am assuming is very badly corrupted), maybe that would fix the problem? I appriciate any help you can give!
