SP3 potential problem

Hello,
Not sure if this is the appropriate newgroup to post this question. Please
re-direct me if not. Recently, my computer was updated with SP3. Since that
time I started having intermittent problems with the hot keys on my laptop,
namely the Fnkey and the end key which toggles my speakers on and off. The
functionality is there but the display that would appear on the screen no
longer is. Dell uses an application called Quick Set that controls this
functionality. They say that they have had reports of problems with this
application after SP3 was installed. If this is true, is there any
work-around. They want me to reformat my HD which I really don't want to do.
Any suggestions?
