The PS2 keyboard in my computer has stopped working! After booting in XP,
keyboard does not respond and the device manager shows keyboard device with a
yellow bang sign. When I check the properties of this device, it says that
device is not working properly because the registry is either damaged or
corrupted. I tried uninstalling the device from device manager and
reinstalling it from a reboot. But it did not work. I then uninstalled the
keyboard from device manager, unplugged the keyboard and rebooted in XP. But
the device manager showed a keyboard with a yellow bang sign when there was
no keyboard physically connected!

Help me please.

Check that the keyboard drivers are installed correctly -
ControlPanel/Keyboard... see if the driver (Standard Microsoft Keyboard...
is present). While in ControlPanel, make sure that the Language and Regional
settings are set to English or whatever version XP you have.

Another thing to try is to delete the KBoard driver in Hidden device (in
Hardware manager/ Show hidden devices) since XP keeps a copy of any driver
it needs to boot. Might be a corrupted one so it will reinstall from CD or
CAB.

Otherwise, try another keyboard that works and see what you get.

SOLUTION!

This worked for me and the guy who posted it. We had the exact same problems assuming you are showing error code 41. Might still work with code 39 as well.

"I solved my problem by removing an item from the UpperFilters for the keyboard in the registry. It's under:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\4D36E96B-E325-11CE-BFC1-08002BE10318
There was an entry for keykey which was leftover from spyware removal action."

That worked great I had the same problem and spent the last 18 hours trying to find the problem , Reloading drivers running scans and nothing worked , I was close to redoing my whole system and i found your advice. There was an added word that did not look right before kbdclass in the upper filter and removed it and left kbdclass in there because I knew that was for the keyboard . mine was error 39

Thanks

This worked for me! I had a Code 39 error and found an entry before kbdclass and removed it and my laptop keyboard now works just great. Thanks so much.
