I have two computers, both run XP pro with SP2. One computer shuts down in 10 seconds,that's lovely, but this one takes over a minute to shut down?? Any ideas??? I have tried the microsoft update, and the patch for system hangs to no avail. Anuthing else?? Also tried resetting the root hubs as was suggested but again still the same. It starts up fine,but hangs on shut down.???????
