Start with the basics - is one mouse and keyboard the only input devices
you have? Are they plugged straight into the motherboard sockets?

I ask this as I have just tried running the mouse through a usb hub that
turned out to be flaky causing it to have erratic behaviour. I have also
seen a second mouse and a wacom tablet interfere with a mouse. The two
mice came from a wireless keyboard/mouse combo where the mouse was
useless (actually it was a logitech wireless combo, the mouse was going
to sleep even as I was using it) - the wireless transceiver always
responded as a mouse and keyboard even if the mouse had no battery to
respond.
