Tried it but the external drive remained completely invisible - and also
made the USB cable modem invisible thus killing my net connection. I
tried it again having ONLY the external drive plugged in but still nothing
showing..

Someone has recommended I reload Windows XP over the new motherboard.
Would that really make any difference seeing that OTHER USB stuff works
ok?

Before you do that, have you started in Safe Mode and deleted ALL USB
devices? You have not given the model of your motherboard, so I have no way
of checking what USB chip you have, but if it's NOT INTEL, thats the
problem. When you changed the motherboard, best is fresh install, next best,
delete ALL onboard devices and let windows re-detect at next boot.

I don't use Windows XP, but the fact that your cable modem disappears
after connecting your external drive suggests that some current limit
is possibly being exceeded.

FWIW, in Windows 98SE, after connecting a flash stick, I go to DM ->
USB Controllers -> USB Root Hub -> Power -> Power Properties. I then
see the following:
