Try unistalling the touchpad driver, and reboot. The machine will find the touchpad and reinstall the driver automatically. These have a tenancy to glitch when using an external mouse, and this should clear it up. Let me know.

Pls check that the press button on the top of touchpad, most probably its disabled by being accidently pressed.

Do not check the check box as leaving the touchpad enabled while using an external mouse will not cause any harm.

Go into your windows device manager.
Search for your touchpad (should call synaptics input device)
give it a right click and disable the device.

I rather think that your mainboard is having problems, tried a bios upgrade and the latest drivers yet?
