In reading several posts I note mention of using the 'Event Viewer' as a tool for problem solving. Since I currently have a 'Boot Up' problem I figured this may be a good thing to look at. Note that I have looked at the Event logs for the boot issue previously. However, this P.M. I thought I might look again to see if I could figure out where my 'Boot up' was taking a nose dive and starting over again. Damn!! This 'Event Viewer' has five entries and I assume you all know what those 5 are. The old double-click trick on any of them has the same BAD result. Lord, what kind of crazy crap is this!! The resulting informative box states, "Unable to complete the operation on '----------------------------------' (whichever one you clicked on)" Followed by the wonderful news that "The INTERFACE is unknown". It's a wonderful life is it not?? So full of surprises to make your day! So it would seem that my Windows XP has decided to 'Disavow any knowledge of the Event Viewers action' or perhaps existence also!! Anyone seen this trick before?? Really hate the thoughts of another re-install. Maybe this is an undercover thing by Microsoft to download updates that screw some things up that will prompt you to rush out and buy Windows 7. I intended to do that soon anyway, but this may convince me to do it sooner. THANX!! And, pardon my bad puns but I could use a laugh!!
