Posted this on the Yahoo forum today ....... posting here as well in the hope of enlightenment!
All was fine .... until today and the CNC mill stopped or rather kept
hicchupping. Checked the Laptop with the driver test and the result
was abysmal .... not a good graph at all with pulse rates often as low
as 500 or so. Obviously (I think) affecting the drive motors.
Tried all the usual optimisation recommendations with no effect....
but why should it change from working OK anyway?
Put the laptop back to as it was and did another few driver tests and
got good results with pulse rates up 50,000 plus ..... did a few more
and back to crap again. Bursts of terrible pulse rates.
Why this variation? No other programs running except background
services which have not shown a problem before.
Going bald with pulling hair out!!

Solution to problem found! ...... believe it or not the cause was simply due to an unplugged floppy drive in the USB port. Why a portable device should cause the error I know not but anyrate I am back in "happy bunny" land :)
