Running XP Home on a Dimension 4500.  In the Windows folder there's a folder named PCHealth.  Any idea what that's for?  If it's for something like remote diagnostics, which I don't need or want, can I make it go away?

There's another folder in Windows there named 'DellPCH'...  Any idea on that one, and can I make it go away?

And lastly, a folder named 'minidump' with three .dmp files!  What are those, and do I need them?

Thanks,  Bob
