Any one help?


Try uninstalling the drivers and reinstalling them.

To determine if it is a software issue, booting an
alternate OS may tell you something. Either a Knoppix
(knopper.net) or a Ubuntu (ubuntu.com) CD can be used
to boot a computer. If the mouse still jumps all over
the screen, then you know it is a hardware issue.
If the mouse is smooth, then return to WinXP and
experiment with drivers or whatever.
