I have a four year old Compaq CQ2103WM computer with a 139GB Hard Drive and 1GB Memory. I have been having problems with the mouse not working or freezing for some time now. Now the mouse doesn’t work at all. I tried changing batteries, using different USB ports both on the computer itself and a new USB hub, changed the mouse several times, including 3 new ones. They worked fine on my other computer but not on the Compaq. When I plug in a mouse (including the original mouse) I get a Found New Hardware message and the New Hardware Wizard opens and asks for an installation CD. Then I get a message that the new hardware was not installed properly and may not work. Since the pointer no longer moves I can’t do anything. And the message stays onscreen until I turn off the computer. I started having trouble with the mouse after removing a Rootkit in November 2012. The mouse would stall or freeze and then start working again, sometimes after rebooting or turning off the computer. The Devise Manager says the mouse is fine and found no problems with it. I can’t get the pointer to move at all now. Does anyone know how to get my mouse working again? Thanks for any help offered.
