My son uses an older Dell, and the left/right arrow keys weren't working, so he disconnected the keyboard and connected an old Packard Bell keyboard. That didn't work, so he reconnected the Dell keyboard which now doesn't work at all. I've checked the connections, and they are fine. To add to the problem, the computer runs on Windows XP and requires a password before going beyond the initial screen. (a password that can't be typed in because the keyboard won't work) Anybody know what I should try next?
