I would try a new mouse or at least a different one. At one time I had a mouse that I was clicking to hard and damaged the click. If it's has a USB Connection try a different location.

found this info on other forums about a Dell latitude I will list all of the various ways that I saw; you can go to Control Panel > Mouse and select the Dell Touchpad tab. There should be a Device Select icon which will give you the option to turn off the touchpad and/or touchpad buttons. Alternatively, for those who want to turn off the pointing stick and/or pointing stick buttons, there are also options to disable or enable those. *Start-->Settings--Control Panel double-click mouse and there's an option there to disable the touchpad *"For all of you having trouble enabling or disabling the touchpad: Turn on or off the Fast Initialization button under hardware properties for the Touchpad. Fast Initialization = On, then reboot, you are now able to turn the touchpad On or Off from Mouse Properties Hope this helps, it was a PITA to figure out." *Just go to control pannel and double click on 'mouse'. There should then be a tab called 'Touch pad' and click on that. There should then be an option 'Tap off when typing' enable that and your problem should be solved. It also said that if you do not find those options there then it is possible your touchpad drivers are not installed which would allow you to make the changes. "If the control panel only shows things about a "mouse", the touchpad drivers are not installed. You could try www.synaptics.com for drivers." found this on the dell site *Customizing the Touch Pad and Track Stick You can use the Mouse Properties window to disable the touch pad and track stick or adjust their settings. Open the Control Panel, and then click Mouse. For information about the Control Panel, see Windows Help and Support Center. In the Mouse Properties window: * Click the Device Select tab to disable the touch pad and track stick. * Click the Touch Pad tab to adjust touch pad and track stick settings. Click OK to save the settings and close the window. I hope out of those maybe something will work
