There have to be screws holding the mouse together... have you tried checking under the plastic sliders that are glued onto the bottom of the mouse?

This is a great option if you want to do everything yourself. Godaddy is what I use and they take care of all the updates and server settings for a very fair price. (less than the time it used to take me to update my servers at home)
Good luck

Well this problem happens to be a universal one although I must say if you want to solve this one all by yourself then u've got to open up back cover of your mouse ( using a screwdriver ) then remove the dust wherever u find it. Find out which circuit is being obstructed by the filth and if there is something obstructing it then simply use a blade to remove the dust so that the connection between various ends and terminals is again possible. However if the problem persists then give it to a hardware specialist which I doubt would be able to solve the problem ( instead he would give u a new one ) Dude buy a new one instead how costly could it be ?? If yours is in warranty then get it replaced !!

hi, try another mouse on your pc and see if the problem is the same and if not change your mouse.

You only need batteries for wireless optical mice.
Just plug the mouse into a USB port and let the operating system detect and install the drivers for it.
It will let you know that the device is ready to use in the system tray (bottom right hand side of the screen).

Go to the start button and click on control panel.The, click on hardware or sound options and click on "mouse". When you get to the options window click on hardware. Find the mouse that you are trying to get to work. Then click on propoerties. In the next window it should state that the device is working properly. If it shows that and still doesn't work reboot the computer. At that point It should work.

Hope this helps!!
