Keyboard

Silly question time…the other day when I rebooted my pc my logon screen came up and I was unable to type, also my mouse cursor did not show up. If I remove the keyboard and reboot the mouse will work fine but I can’t logon without the keyboard. I tried bootin in safe mode and the same thing happens. Strange thing is if I boot to DOS I can use my keyboard to type no problem…I tried to boot to last known good config but nothing.
They keyboard is a ps/2 if this matters.
THanks

Ask a friend if they can bring a keyboard over for a few minutes to test. It might be just an old keyboard/wiring.

have you tried powering down, unpluging the kboard, replugging it in and power back up?
