Hi Jim,
That was some size log (15 - 20 minutes to download ) and unfortunately it shows that Windows has a massive amount of errors, so bad in fact that it may take a fresh install to put right, before that is suggested though can I ask what type of media was used to install the present Windows 7 OS as in a full retail or OEM disk, a downloaded ISO or a burned copy that you created yourself.
Things that could be tried first include a Repair Install details here or the less favourable uninstalling SP1 and then reinstalling it, the latter is less favourable because it may not reinstall.
