Well, I blame norton for your problems. google norton and problems on the web.. you'll find thousands of issues.

Smartest thing yo can do, it turn norton OFF, and THEN install sr2.1, and THEN see if you are still having problems.

Odds are, norton didn't allow something to be installed properly, and that's wjhy you are having issues.

Heck, even search for norton here.. you'll find dozens of peopel to tell to to get it off your system as fast ads possible. In some cases, you'll see a system speed increase of up to 20% JUST by not having norton installed.

Just like vista, norton does way too much hand holding an dprotecting, and check every dsingle file every single time it's access, and that's a system killer.

Way too many people take way too many things way too seriously.
