Is the stepper motor for the axis that has quit moving making a whining noise ?

You may be lucky.

Mach3 seems to work best with the older PC's (~1GHz) so I don't think you would notice any difference between 2GHz and 3GHz.
What I have found to be more important is a PCI graphics card with 1GB or greater memory (Mach3 is heavy on graphics and when it comes to large files, turning off the toolpath display may be an advantage).

I would be most grateful if you would zip it and send to my email (address below my avatar).

My solution is to  create a separate Gcode program for each different operation then run them consecutively after changing tools etc. (take care to use the same datum [X0,Y0] for each separate program).

Very very basically there is an incompatibility -  laptops use various power saving features and Mach3, when using the parallel port, places a high demand on processor and graphics. I have one old laptop that works beautifully using the parallel port and two newer laptops that just don't work well with pmcia parallel port cards. This situation was discovered way back by Artsoft - the result is that laptops are not supported for parallel port operation.

Please post your .xml file this will enable us to check your Mach3 settings.

each one of the gantry motors has its own driver but signals to the two drivers are parallel and come from the (Y) Chanel.

If you are still connecting it that way (not recommended) then maybe the Y Channel does not have sufficient voltage/current to drive two motor controllers correctly ?

Perhaps carefully check the connections and cable to that dodgy motor - could be a high resistance or even open circuit.
