After allowing the last few updates to self-install, I have found that when clicking on the IE icon, it pauses, then does nothing. the start menu will populate, with some access to some internal programs, but IE and other programs will not launch. This is a new factory-installed box, with no other browsers installed. AVG Free, Office 2003, skype and CC Cleaner are the only non-OEM programs. computer worked fine until this past week, I have had to use system restore to roll back to last week to have any functionality.
