Hi mercurysony,

Go to Device manager and expand the Mice and other pointing devices.
Does it list a pointing device, if not and a PS2 mouse is listed try the following.

For XP.

Right click once on PS2 mouse and select properties.

Select the 'Driver' tab and click on Update driver.

A new Hardware Update Window will appear, select Install from a list or specific location (advanced) and click next

The window now changes select 'Don't search I will choose the driver to install' and click next.

If 'Alps Pointing-device' (possibly Alps Pointing-device for Vaio) appears in the new window, select it and click next.. (if the 'Alps Pointing-device' does not appear in the list remove the tick from 'Show Compatible Hardware' and select Alps Electric from the Manufacturer column then 'Alps Pointing-device' (possibly Alps Pointing-device for Vaio) from the model column and then click next.

Wait for the driver to install then click Finish, a System Settings Change window should now appear prompting you to restart your Computer and click Yes to restart.....
