Standby Issue

I have a standby issue with my machine since I loaded "Front Page 2003".
Before I loaded frontpage my machine would enter "Standby" just like it
should. Since I loaded frontpage the machine will not enter "Standby". I
uninstalled frontpage and the machine still will not enter "Standby". Are
there any known issues with this and how can I correct it. The other
question I have is after I uninstalled frontpage the directory and some files
remained. I tried to delete them but they won't delete - it says they are
being used.

Thanks
