PC upgraded - now keyboard doesnt work

[kran-k]

I upgraded one of my computers at home, mainly by installing a new motherboard, cpu, and memory:

Motherboard is ASUS M2A-VM
CPU Athlon 64 x2 3800
2x512 Super Talent DDR2 800 RAM

(Old cpu was a pentium 4 2.66, running on XP - dont think this is relevant)

But now the keyboard (PS/2 type, non-usb) does not function and I cant run the setup for the new motherboard.

One possibility is the old power supply (ANTEC SP-400), although I think it should be adequate for this new system.

Thanks in advance for any help.
