Do you have a wired mouse or other pointing device (does not sound like
a laptop or there would be a few available) for comparison?  I imagine
"noise from my wireless mouse" to refer to mouse _movements_ and those
do not just exercise the mouse and its USB connection but also the mouse
cursor display.  If the problem is actually with the graphics
controller, using a different pointing device could provide a clue.
