Well, the reason I wanted you to post the list was to see if any virus
or spyware would have shown as being present, at a quick look I don't
see anything there that looks like malware so that would seem to be
eliminated as a cause of your slowness problems. One big hog that I see
there is Symantec, you may want to reconsider your use of this AV
program, there are much lighter AV programs available, Avast for one is
much less demanding than Symantec.
Other than that you will just have to go thru the list and consult the
web sites that we pointed you to earlier and decide for yourself what it
is that you really need running, if you see things in there that you
only use once in a blue moon then you should remove them from the
startup location. To disable the unneeded items you can go in the
programs that you want to remove from the startup and see if they have
an option to turn off the boot time autostart, the well written and
graceful programs always give an option to turn off the start at boot.
For the not so well behaved programs you can use utilities like Autoruns
that Daave suggested, or the built-in Windows Msconfig utility. I also
like this little utility,
http://codestuff.tripod.com/ it is small and
easy to use, it has a very nice GUI, plus it will keep a list of what
you disabled so it is easy to later undo changes if you want to
re-enable them. Keep in mind that almost all of the utilities that you
remove from the list will still work just fine when or if you start them
manually.
As a first candidate for removal from your startup list I nominate
ati2evxx.exe, look here for it and see if you really need this running:

As for the services just use the Windows Services Management Console to
change the startup type of the unwanted or unneeded services or look in
the software that owns the service to see if it can be disabled. You
can print the output list from the Net Start command and use it as a
record keeping aid to keep track of the changes that you make with the
services.
Is your computer on a home network or is it a stand alone? Are you the
only user or do other users also use it?
