XP-Home, Keyboard CODE 39 - Not responding

[JWW]

Hello,

I am having great difficulty using my computer since I installed an
Officejet 7110 multi-function printer.

P4, 1.8 ghz, 896 Ram,

My keyboard is no longer responding. Device manager shows an
Exclamation point on the driver. ALL other functions are working
normally. I can surf the net and read emails using the mouse. Only
keyboard is affected.

Changed keyboards - no change.

Switched to a USB keyboard - no change.

Switched to Safe Mode - did not work.

System Restore to a point before the new printer used to fix the
problem, but no longer works, and in fact all the restore points are
now gone from the system.

Reinstalling the keyboard does not work.

We discovered that the mouse and the keyboard are apparently trying to
use the same interrupts. We uninstalled and disconnected both and
installed only the keyboard. Did not fix.

I Installed a back-up drive that was cloned 12 months ago, the
keyboard works proving the hardware is good.

How do I get the Keyboard to work again?

I have since purchased a new machine and now have both new and old on
a network allowing me to access my files on the old machine.

I am lost... Thank-you for any suggestions.

JW

Try uninstalling the Officejet printer, to see if the keyboard comes back.

failing that if the operating system you are using like ME and XP have a
restore function then restore to a date before the problem started.
