I have Altec Lansing VS-3151 speakers to go along with my Compaq 7500 than runs on Windows XP. When I recently turned on my computer a window popped up that said new hardware was found. I ignored it and later found out that my there was no sound coming from my speakers and songs would not play. But when I finally paid attention to the window that said new hardware was found, it stated I need to have the disc that came with the speakers to complete the installation. But I don't have the disc, so is there anyway of installing my speakers without having the CD that came with the speakers. I'd appreciate any help if possible.
