For a standard trackball mouse, unplug the mouse, turn it over and then twist the retaining ring counter-clockwise to remove it.

Remove the trackball inside the mouse.


Clean the trackball with warm water and dry carefully. Clean the rollers inside the mouse with a cotton swab dipped in rubbing alcohol. Replace the trackball, then secure it with the retaining ring.


Clean the outside of the mouse with rubbing alcohol and a cotton ball.


For an optical or wireless mouse, clean the bottom of the mouse and the surface it sits on with a damp cloth.

Solve Hardware Problems


Make sure the mouse is connected properly.

The connector will either be USB or PS/2. A PS/2 connector is color-coded green and can only be inserted in one direction.


Check for any bent or broken pins or damage, then carefully plug it in, making sure the connection is secure. Reboot the computer.


Connect the mouse to another computer, then reboot the PC.

If the mouse works after testing it on another computer, the problem is most likely with your PC or operating system.


Also, try a different mouse on your computer.

If there is no PC freeze, your mouse is probably malfunctioning.


Switch to a different USB port. Sometimes mouse freeze will occur if the mouse is connected to a USB hub.


Connect the mouse directly to one of the USB ports on your PC.

Try different ports until you find one that works.


Replace the batteries.

If you have a wireless mouse, replace the batteries with fresh ones.


Also, try using a different kind of mouse pad.

Sometimes surface imperfections can interfere with the operation of a wireless or optical mouse.


Install more RAM or memory.

If your PC doesn't have enough memory, PC mouse freeze may occur when you are running resource intensive programs.


Installing more RAM will help your PC run more efficiently.

Solve Software Problems


Check for device conflicts. When you install another device on your computer, it can sometimes conflict with a PC mouse.

Remove any new hardware and drivers you may have installed, then reboot the computer.


Reinstall PC mouse drivers. In Windows, open "Control Panel" then "System."


Select the "Device Manager" tab, then scroll to and select your mouse.

Uninstall any drivers that are listed.


Unplug the mouse and reboot the PC.

Plug the mouse back in, reboot the system, then allow Windows to reinstall the drivers if prompted.


Remove viruses.


PC mouse freeze and other serious problems can be caused by viruses lurking on your system.Set the program to run a complete scan every 24 hours.

Also make sure the virus definitions are updated regularly.


Turn off video acceleration. Sometimes video acceleration can cause PC mouse freeze.

Go to "Control Panel," then click "Display," and then "Change Display Settings."


Click the "Advanced Settings" button, then the "performance" tab. Set the acceleration slider to "None," then reboot.


Repeat the process moving the slider up one notch until you have the maximum amount of acceleration with no mouse freeze


hope this helps

My G5 freezes constantly. What can I do.


Try running Apple Hardware Test on the machine (it's one of the discs that came with the machine.) Also, if it's freezing by showing the spinning rainbow cursor (beachballing) you may have a failing hard drive. That wouldn't be uncommon for how old the machine is.
