By saying "scroll wheel USB mouse" can I assume that it a wireless 
mouse? If not a wireless mouse then ignore following :-) . Otherwise 
consider these:

* is the receiving unit under or behind a monitor? I had a similar 
problem when the unit got pushed under and behind the (LCD) monitor. The 
monitor's electrics interfered with the signal;

* is the battery in the mouse fully charged? (I use rechargeable 
batteries which is why I ask the question.) A few days ago the mouse 
stopped working - period. The keyboard was OK and was responsive, the 
system was still running but the mouse was 'deaded'. With the speed of 
Superman circling the earth looking for Lois Lane I deduced that the 
problem may lie in the battery - and this turned out to be correct :-) '

* not really applicable to your situation, but not that long ago the 
mouse became lethargic: it would move at a snail's pace and I had to 
move it several inches just to move it an inch across the screen. Not 
normal and not nice :-) . I don't really know why I did this, but what I 
did was to blow into the 'ole wot the laser uses to detect movement; 
just a single, quick blow job - and the mice started to work at its 
normal well behaved way.
