Vista - 'keyboard error or no keyboard present' boot up error

Last year I built my PC and all has run perfectly since until yesterday.

I turned it on only to be greeted on boot up by the error message

'keyboard error or no keyboard present'

This is before it has even fired up the Operating system so I guess its hardware based.

The keyboard is a usb connected Logitech wireless usb keyboard and mouse.

As the PC has no PS2 ports I will borrow another keyboard from work to see if that makes any difference.

I have already tried removing the battery and resetting the cmos on the motherboard but to no avail.
I now get two error messages ...the keyboard one and the default bios settings one.

Only difference in operation is that of late my girlfriend has started turning off the power switch at the rear of the pc after closing down the operating system so our little boy cannot turn it on.
Would this be enough to fry or foul up the mobo??

Mobo is only a year old like I said so so hopefully its not terminal!!!

Help required please!!!!!

Your keyboard may have failed.

Is it connected by USB, and if so is the BIOS set to support USB keyboards?

After you clear the CMOS you need to go through and check that all the
BIOS settings are correct for your system.

Turning off the system power means that you are relying on the
motherboard battery to maintain the CMOS settings and all your devices
will be reset when power is restored. If you have never turned off the
system power before you may now have revealed a problem which has always
existed.

The motherboard battery might be defective.

Sometimes, failing external or internal devices generate electronic
noise on startup which confuses the BIOS. Disconnect everything
non-essential and see if the problem persists.
