How do I fix this mouse movenent bug

KENNITHH,
Welcome to SF. Please fill in your system spec's and tell us the make and model of your mouse.

Not sure but looking up this mouse at Logitech it's not a W7 mouse. Vista instructions below:
"Download Instructions

This device uses the native drivers when used with Microsoft Vista™. If you do not have Vista, please select another operating system from the dropdown list above.

This product originally shipped with either iTouch or MouseWare, which are not compatible with Vista. We strongly recommend to uninstall iTouch and/or MouseWare prior to migrating to Windows Vista. After iTouch and MouseWare are uninstalled, the basic functionality of your devices will be provided by the Windows native driver."
Do you have another mouse you can try out? Have you tried another usb port on the back IO panel only? Blast some air to clean optical lens?

Thanks for the search but I don't have iTouch or MouseWare , I think it has been installed by the native windows7 driver.

Do you have another mouse you can try out?
Yeah, I've just tried one, a Value Optical Mouse M-BT83 (USB port) but this one just trips when I do the fast movement lol.

Have you tried another usb port on the back IO panel only?
Yes and I think it was even worse , I was on this page and moved the mouse fast and it started clicking too and closed this page so now I'm typing this for the 2nd time

Blast some air to clean optical lens?
Done that too (had 1 hair in it yesterday) but still has the issue.

I also tried doing the sens very high and it does it there too, maybe I should make a small movie to demonstrate what it does? Yeah I'm going to do that, I'll post the video in 10 minutes

EDIT: Ok I've tried just the exact mouse (I've got 2x Logitech M-SBF-90 Black Optical Mouse) and same issue, even the same movement.

Here is the video of me recording my mouse : http://www.mediafire.com/?p83au8b1mu4ek14 (placed it in a ZIP file for filesize)

Hope it makes something clear but I keep thinking it mathers cause the mouse aint made for fast movement but I could be wrong, I don't know much about hardware.

KENNITHH,
Now I think you're on to something. Go through all your sleep settings and turn them off, screen save yes, sleep mode no for the time being. Then go into your start up menu and hunt around for all the programs to drop that don't need to load till you ask them too. This is a setting issue but having never had this issue other than on an older less powerful system I had all programs in start up mode and it caused similar mouse issues.....somehow with the power your rig has I can't see even that being the problem but crazier things have happened. Stay with it because you'll happen on something that makes the difference.

Take them out one at a time and reboot and play around. Only load those absolutely need program to run AV and the like. All else can be opened normally via All Programs or launch icons. Then when you've found the culprit then set up the sleep mode to fool your dad.
