Hi all

I have a Microsoft usb keyboard that has stopped working. When I turn on the PC it goes to the logon screen and I can type my password in. After that it will not work in any program. I can not type a thing. Wireless mouse is fine.

I have tried virus scan......no issues. I have tried unplugging keyboard rebooting and replug in. I have tried deleting device in device manager and allowing a reinstall

What next?
