When plugged in to a spare usb port on the back of the cpu, it is not recognised and the mouse and keyboard cease to work. In fact, the whole computer freezes and has to be just switched off rather than shut down.
When plugged in before booting up the computer, the monitor goes black and all action ceases half way though booting up.
I tried using the 'add new hardware' wizard - but of course it all seized up when I plugged the [bleep] thing in, so no luck.
There are only 3 word docs on it at the moment, and I'm sure any (unlikely) viruses in these would have been picked up by the other two machines. This computer is only just over a month old, and is running windows xp.
Any ideas? I'm completely baffled!
