When you say you've gone over the hardware and found nothing wrong does
this mean you've swapped out various hardware for other hardware?  It could
well be that any part of your hardware is on the way out but you just can't
detect it.  Wear and tear could be the cause here?  In this case there's
not much you can do other than swap out each and every bit of your PC to
see which bit's causing the problem.  You could run diagnostics tools first
I guess but you may have already done this?  That said, does it only happen
when you CTRL-ALT-DEL and lock?  If so, there are some tools from
Sysinternals that could be of use here.  They're called procmon and regmon
(www.sysinternals.com).  Run both on a healy PC to see what happens when
you lock and then unlock your PC (it'll show you which files are accessed/
which parts of the reg are accessed).  Also run this on your faulty system
and see if there're any major differences (e.g. hangs occur when accessing
a particular part of the registry or a particular file).  I find these
tools very useful for odd Windows problems.
