I have found that the best way to adjust your mouse settings is to create a control panel in your bottom toolbar scroll to the bottom of your screen right click you will see an array of options select the toolbar option then select desktop
then you will see the desktop in the bottom toolbar select the 2 >>arrow heads then all control panel items then select mouse this is in WINDOWS 7
in XP you will have to select the new toolbar option once you have that a browse option select my computer then control panel then a control panel option will be in the bottom toolbar
Click start right click on my computer select properties device manager control scroll to mice and pointing devices you might see a yellow question mark? right update driver
Click on >> control panel all control panel items mouse you should see 4 tabs buttons pointers pointer options and hardware under hardware you have options to troubleshoot also you can select properties under driver you will have the options update driver rollback driver or uninstall in xp.
In windows 7 click start control panel hardware and sound mouse you will see the same tabs and options as with xp

Enable a Mouse for a Laptop
Without the ability to drag and drop and point and click, a laptop computer is merely a desk ornament.
Most laptops are manufactured with a built-in mouse in the form of a touchpad.
If the touchpad fails or if you just prefer working with a mouse, it is easy to enable a mouse for use with your laptop.
Purchase a mouse that is compatible with your laptop.
You can find compatibility information on the manufacturer's website.
If the mouse is wireless, make sure that the USB receiver is included, or purchase it separately. The mouse will not function without the receiver.
Insert the batteries in the mouse if you are installing a wireless mouse.
The battery compartment is generally located on the bottom of the mouse.
Connect the USB mouse to the USB port on the computer.
If you are using a wireless mouse, connect the USB wireless receiver to the USB port.
Turn the computer off and then on again if you are enabling a standard mouse with a wire.
This will instruct the computer to run the "new hardware" wizard, which will walk you through the installation of the mouse, and your mouse will be enabled.
Turn the wireless mouse over, and locate a small indentation with a button.
You may need to use the tip of a pencil or pen to depress this button.
Simultaneously press the button on the mouse and the small button on the USB receiver.
This will initiate communication between the mouse and the receiver.
Hold the buttons down for about 5 to 10 seconds until the light on the mouse comes on.
Test the connection by moving the mouse.
If the cursor moves, you have successfully enabled the mouse.
If not, check that you have the batteries installed.
Try pressing the buttons independently of one another.
Press the button on the receiver until the light blinks and release it.
Press the button on the bottom of the mouse until the light on the mouse is lit.
This should enable your wireless mouse.
