It could be a sign of an aging OS. Windows, over time, will become kind of bloated. It will get more and more registry entries over time, slowing bootup times and general performance.
To help the effects of aging on an OS, try the following:
-Make sure you defrag your hard drive at least once a week.
-Uninstall programs that you dont use anymore.
-Scan frequently with updated virus scanners and spyware scanners
Also, I recommend reinstalling Windows at least once a year. Although there are registry fixers out there that should help to clean up the registry, I still like the idea of starting fresh every once in a while.
