Make sure connections are good and maybe try a different USB port . Reboot and see how you go . It would help to know what kind of machine you are running . Laptop or desktop , for a start ...

Try a different PS/2 keyboard.
Try a different USB-to-PS/2 adapter.
Try the current PS/2 adapter on another computer.
Have the PS/2 ports on this particular computer ever worked?
Are you sure you've connected the keyboard to the correct port on the motherboard?
Are you sure you're using a keyboard USB-to-PS/2 adapter and not a mouse adapter?

Keep in mind that the keyboard has to be designed to work with both USB and PS/2 interfaces. The adapter converts the physical plug, but the communication protocol is very different between USB and PS/2, so the keyboard itself has to be designed to work with both types of interfaces.

Many new USB keyboards will work on a PS/2 port, but I suspect that older PS/2 keyboards like that Dell just won't work with USB -- it wasn't designed for it.
