KB/M driver issue?

listen to this. I installed a computer for a client, win xp sp3
i installed it originally with a ps2 kb/m
i bring it in to the office to set it up
kb/m wont work,
wireless USB wont work,
wired usb wont work
and i had a ps2 ball mouse
didnt work either
prompt however in windows did come out
"windows has found hardware blah blah blah"
"connect to windows update to search for updates?"
i cant click or do anything
now, understand this, both kb/m work in bios


What should i do?

you can check for USB emulation under BIOS if u had that option and it should be enabled and u complain about the ps/2 mouse also not working,only way to resolve this is by reinstalling OS,and xp sp3 has lots of problems install sp2 itself...
