very slow startup

It's me again.. 2 weeks ago I had the problem of very slow startup..
turned out to be the network WLAN driver I loaded from Windows Update.
I removed it, installed a good one from the manufc. Well it ran fine
for a week.. I reinstalled the good driver and it worked fine for a
couple days. This is getting old...

.. Here is a revised edition of my bootlog, only "did not load"
showing... does this make sense to anyone?
NOTE: I don't have a floppy or CDrom on my notebook...
