I've recently noticed that my WinXP Pro Task Manager is always (as far as I can tell) showing my CPU at 100 percent usage.
I have not noticed any glaring or obvious O/S or Application(s) problems, but I am nonetheless concerned.
My questions are as follows:
1) What could potentially cause this kind of apparently-constant reading?
2) What, if any, diagnostic procedures should I/could I execute (besides the obvious shutting down of running apps/processes one by one)?
3) What are the potential side effects and/or dangers of such a reading?
4) I recently installed Win XP Service Pack 2 (beta), could that be the “problem” (I do not recall the exact chronology, so I'm not sure which came first, the service pack, or the 100 percent usage)?
a) Are you aware of any Service Pack 2 “known bugs” listings?
Thank you in advance for any and all insights you might be willing and able to provide.
