Laptop Questions? Ask a Laptop Technician for Answers ASAP!
Hello there, my name is ***** ***** I will be assisting you today. Do you have a mouse plugged in to your laptop, or are you using the built-in touchpad mouse? Is the behavior the same with either mouse? I would go in to Control Panel > Mouse and look at the settings in the "Mouse Properties" window. See if the settings in the "Pointer Options" tab show a setting of "fast" for mouse speed. Check the other settings to see if anything else looks awry. Let me know how it goes.
So you have tried several different mice with no change in behavior? Does the behavior stay the same when different users are logged in?
I would also suggest disabling the built-in mouse/touchpad, just to see if it is the item which is sending "random" inputs.
