If these are not helping when you turn on the pc, hit f8 and boot into safe mode. If you have multiple users on this pc, be sure to select the administrator account. Once you are in safe mode, hit the windows globe (formerly known as start ), type run , select that, it should be the first item at the top , then type cmd and hit ok.
