Ok here we go i am having problems with SP2 when I click on the start bar such as my documents, my pictures etc... my computer acts as though it is shutting down like the start bar disappears then re appears and nothing happens. The same thing goes with all items on the right hand of the start area. Such as control panel , my computer all of it. I have done everything everyone says and run all the spy sweepers possible prior to install. I uninstall SP2 and have no problems. Everytime I install SP2 I get the same results.
