I'm running an HP desktop (Pavilion Slimline s7600n) with Windows XP, used mainly for e-mail, internet, and MS Office applications. Lately, the unit is shutting down unexpectedly -- the screen 'Going to Sleep' appears, then immediately goes into restart mode. Very annoying, not to say unexpected loss of documents in process, etc.
I would welcome any and all suggestions on this problem and how to diagnose the issue.
