OK, late last night (UK time) I downloaded the complete MSAS program to my
local drive.
Disconnected my ADSL connection.
Uninstalled the existing MSAS configuration using the link in the program
group.
Ran Registry Mechanic V5 to see if any debris had been left from the
uninstall.
RM V5 found over a hundred custom controls and all the program
shortcuts still in place which I then asked RM V5 to delete.
Used Explorer to see if any MSAS folder structure was still evident and it
was, with a good few files still there including those in the sub-folders
shown below. I deleted these too.
I then rebooted the laptop.
I then turned AVG Free off.
Ran the install for MSAS.
Rebooted the laptop with all functions allowed to run.
I then ran another Full Scan from MSAS in normal XP mode overnight.
This morning it reported a clean system (As it has done all the way
through).
I powered down the laptop and left for around twenty minutes.
I booted the laptop and timed the boot process (55 seconds to a state
where I could load an application).
I then actioned a shut down and restart, and again timed the reboot
process (60 seconds to a state where I could load an application)
MUCH BETTER!
I'll be keeping an eye on things over the coming weeks/months and see if
this sort of performance remains.
I don't think I'll be doing any Safe Mode tests as I believe there is
something more fundementally wrong with the laptop and power management in
this mode. I've never used Safe Mode in the three years I've had this
laptop, so I can't say if the shut down problem in this mode has always
been there, or it is a more recent issue.
Thanks to all who contributed suggestions.

Hyde.
