Mouse pointer randomly resets destroying my data.

it is 12/31/08. i have been searching for a solution to this problem since i purchased the machine a year ago. i have had the problem from day 1.

the mouse pointer randomly resets. it right-click, left-clicks, scrolls the screen, hi-lites and delete information. basically i cant do anything important because of the risk of loss of data. its a $700 waste of money at this point.

PLEASE READ THIS NEXT STATEMENT CAREFULLY IF YOU THINK YOU HAVE A SUGGESTION:

i have been searching for an answer for a year now. i have done all the "basic" troubleshooting ideas. so take note:

its not the drivers. i have updated them, reinstalled them, deleted them. no change.

its not a virus. it happens immediately after a fresh install of the o/s without internet connection. unless microsoft shipped a virus, its not a virus.

its not the mousepad. i have disabled and uninstalled the mousepad software and the problem is still prevalent.

let me repeat, i am looking for a solution that does not encompass drivers, virus, or hardware malfunction.

with that said, if you have a specific solution relating to the above qualifications, i will be glad to listen. but if your suggestion is a generic "scan for virus", "reinstall drivers" or "hardware malfunction", i have researched these options for months, to no avail.

i need a master diagnostician or someone who has had this particular problem and has found a solution. low-level generic ideas have been done to death.

if i find a solution to this problem here, happy new years to me!

but either way, happy new years to everyone else!
