If it happens with all keyboards, I would wonder about the PS/2 port being faulty.

Does this article help any?;EN-US;203711

Do you have all updates and services packs installed?  If not, do that step first.

Are there any drivers or software associated with the keyboard installed?  Have you tried removing it?

Head to the device manager, find the keyboard and remove it, and then reboot.  Is the problem still present?  Have you tried different manufacturers or are you trying the same model?  Hunt around your office for an unusual keyboard and try that one.

Failing all of this, it's probably a registry problem, although I have no idea where in the registry you would modify it.  I'm sure reinstalling Windows would probably fix the problem, but I doubt you're that desparate.

Good luck,

To determine if the problem is hardware or software:
I'd say you should see if you can turn on/off the numlock/caps lock lights in system bios, if you cannot....and the keyboard works fine on another machine, it's probably a motherboard issue.  Of course you could always try stripping the system to the minimal configuration required for POST and see if it was still happening (just to verify that no other hardware is causing the issue).  Also, have you inspected the ps2 port for physical damage?  If it doesn't work in bios, the ps2 port doesn't appear physically damaged, and the keyboard is known to work on another system, you might also want to try flashing your bios prior to replacing the motherboard.
good luck

I tried all the above and it did not work. Someone I work with indicated that he had ran through that problem before and the only way he solved the problem was reinstalled the operating system. The user who is using the PC in question does not want the OS reinstall, but rather live with the problem. Since Auriclus mention about reintalling windows in his comments, I will accept his answer.

the only problem is at bios level the operating system is not involved at all.  If it's happening in bios, you could take the hard disk OUT of the computer and it would still happen....
