text: help with usb ports please? just bought some second hand computers from work sell out. (reconditioned).one was fine, connected it to the wireless modem in minutes went todo next one but instalation disk asociated with internet said t couldnt find usb  ports.i checked device manager and it doesnt list usb ports there  . the other computer does and this one does too. i have windows xp profesional on all (preloaded when bought).any help on anything i can download to get the ports working please. im not real clever with computers when it involves hardware probs. check the bios settings and make sure that usb is enabled.  bios can be accessed by either pressing f1, f2, f10 or the delete key when you first power on the pc depending on what bios you have, phoenix, ami, etc...
