so, you were able to reinstall the o/s then??? if so, then the keyboard at least worked during that phase. Also, important to know is what o/s. New computer, so it's probably XP or did you put an older o/s on like 95? If so, there is the problem there. You need to install the USB drivers. Give a little more info on the system, pls (also check the bios and disable and then reenable it there if avail).
If you argue with an idiot he will drag you down to his level and beat you with experience.
