Keyboard/mouse not recognized at windows startup
 

Hi all
I dont know a thing about computers but I will try my best
to give you all the details I know.
-according to hubby, my hard drive crashed; we bought used
one with windows 98SE installed on it.
-installed on computer and then tried to install hp
printer, but wouldnt because of the color (needed true
color?). Not exactly sure of why, but my hubby re-
installed? windows 98 from restore disk from previous hard
drive (hope that made sense)
-ever since then hubby says that keyboard/mouse which are
plugged into usb are not recognized at windows log-in, but
does work in BIOS and DOS.

I have no idea what any of this means, except that when we
tried to use serial keyboard it still wasnt recognized.
Any help would be very very much appreciated!!
TIA
:)
