Thanks for all of the replies.
It was the belts. I gave them a clean with soapy water but now there's another problem.
Driving for the first 10 min or so in the morning (after it has been sitting overnight in sub-zero temp) the whining sound is still there. But after 10 min the whining goes away and all is fine. Could there be a problem with the tension of the belts, even though I didn't adjust the tension? I checked the tension when I was cleaning them (pressed the belts with my finger midway between the pulleys and there was about 1/2" of slack).
Whilst it is cold could the belts be putting too much tension on the pulleys/bearing that could cause problems?
However if I loosened the belts wouldn't there be a problem when the engine is warm and would cause slipping?
