What is the "not responding" application? Use Task manager to what process
is "hogging" CPU utilization.

Anyone from time to time. It could be an Explorer window, a Firefox
refreshing, even the Task manager may freeze for few seconds
In Task manager I don't notice high CPU usage: I see an overall use of
maximun 30% and the single applicaltion load up to 10%.
If I run Resource Monitor, I see moments of 100% usage and heavy disk
access, probably swapping, but I cannot detect which application is
the culprit.

I have also seen the other post asking me to move on a Vista forum: do
you want that I move the thread or can we continue here?
