Sounds as you bought a PC that was over-clocked originally? My gut feeling is to reset the bios to default.

Have you tried plugging the usb keyboard into another usb port?

When you installed the keyboard did you plug it in before your booted up or afterwards? Try both ways.

Are you saying that the error message is giving you an option to change it back to default settings but you cannot action this as you have no keyboard?

This message can occur simply because there may be a hardware conflict for some reason - it doesn't necessarily refer to clocking.

Have you got an old keyboard you can try?

first try resetting bios usb settings, other is have you reset the usb receiver and keyboard using button on receiver and bottom of keyboard

Can you get into device manager?

Easy access: Windows Key + break key

Select Hardware then Device Manager

Scroll down to the Keybords and mouse settings and check for Yellow Question marks,if found right click and uninstall.

select any device and from the top line and select Action- Scan for hardware.

This will re-install any duff software settings and should cure the problem.

rdave13 the computers custom built so was never overclocked.

Have you tried plugging the usb keyboard into another usb port? yes tryed all usb ports. When you installed the keyboard did you plug it in before your booted up or afterwards? Try both ways.did it both ways nothing

lister86 , that last link isn't helpful to you or the people that try to help regardless how piqued you are about this problem. Try device manager, find the keyboard and roll back the driver. Uninstall the Logitek driver for the mouse and reboot.

Can I ask...

Did you try to get into Device Manager as suggested in previous posts?

Are you plugging the usb directly into a port or are you using a usb extension cable? If you are using a cable disconnect and plug directly into a port.

Do you have anything else using usb plugged in? If so unplug them.

Have you been able to try your keyboard on another PC?
