Shut down the computer, disconnect the mouse cable and check it for damage, then firmly reconnect the cable.
If you are using a mouse extension cable, disconnect it and connect the mouse directly to the computer.
To verify that the problem is with the mouse, check the touch pad —
If the touch pad operates correctly, the mouse may be defective.
Check the system setup program settings —
Verify that the system setup program lists the correct device for the pointing device option (the computer automatically recognizes a USB mouse without making any setting adjustments).
Test the mouse controller —
To test the mouse controller (which affects pointer movement) and the operation of the touch pad or mouse buttons, run the Mouse test in the Pointing Devices test group in the Dell Diagnostics.
Reinstall the touch pad driver —
See Reinstalling Drivers and Utilities.
Fill out the Diagnostics Checklist as you complete these checks.

A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.
A driver acts like a translator between the device and any other programs that use the device. Each device has its own set of specialized commands that only its driver recognizes.
Dell ships your computer to you with required drivers already installed—no further installation or configuration is needed.
|
|
NOTICE: Your Drivers and Utilities media may contain drivers for operating systems that are not on your computer. Ensure that you are installing software appropriate for your operating system. |
Many drivers, such as the keyboard driver, come with your Microsoft® Windows® operating system. You may need to install drivers if you:
If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver.

|
NOTE: The User Account Control window may appear. If you are an administrator on the computer, click Continue; otherwise, contact your administrator to continue. |
|
|
NOTE: Scroll down the list of devices and check for an exclamation point (a circle with a [!]) next to the device name. If an exclamation point is next to the device name, you may need to reinstall the driver or install a new driver (see Reinstalling Drivers and Utilities). |
|
|
NOTICE: The Dell Support website at support.dell.com and your Drivers and Utilities media provide approved drivers for Dell computers. If you install drivers obtained from other sources, your computer might not work correctly. |
If a problem occurs on your computer after you install or update a driver, use Windows Device Driver Rollback to replace the driver with the previously installed version.
Windows XP
Windows Vista
|
|
NOTE: The User Account Control window may appear. If you are an administrator on the computer, click Continue; otherwise, contact your administrator to enter the Device Manager. |
If Device Driver Rollback does not resolve the problem, use System Restore (see Restoring Your Operating System) to return your computer to the operating state that existed before you installed the new driver.
If using Device Driver Rollback or System Restore (see Restoring Your Operating System) does not resolve the problem, reinstall the driver from your Drivers and Utilities media.
If this is your first time to use your Drivers and Utilities media, continue to step 2. If not, proceed to step 5.

For drivers information, see the documentation that came with the device. |
A message stating that the Drivers and Utilities program is detecting hardware in your computer appears.
The drivers that are used by your computer are automatically displayed in the My Drivers—The ResourceCD has identified these components in your system window.
If a particular driver is not listed, then that driver is not required by your operating system.
|
|
NOTE: If your computer has a Consumer IR port and you are reinstalling a Consumer IR driver, you must first enable the Consumer IR port in the system setup program (see Using the System Setup Program) before continuing with the driver installation (see Reinstalling Drivers and Utilities).

You can restore your operating system in the following ways:
The Windows operating system provides System Restore to allow you to return your computer to an earlier operating state (without affecting data files) if changes to the hardware, software, or other system settings have left the computer in an undesirable operating state. Any changes that System Restore makes to your computer are completely reversible.
|
|
NOTICE: Make regular backups of your data files. System Restore does not monitor your data files or recover them. |
|

|
NOTE: Windows Vista does not disable System Restore; regardless of low disk space. Therefore, the steps below apply only to Windows XP. |
If you reinstall Windows XP with less than 200 MB of free hard-disk space available, System Restore is automatically disabled.
To see if System Restore is enabled:
|
|
NOTICE: Using Dell PC Restore or Dell Factory Image Restore permanently deletes all data on the hard drive and removes any programs or drivers installed after you received your computer. If possible, back up the data before using these options. Use PC Restore or Dell Factory Image Restore only if System Restore did not resolve your operating system problem. |
|
|
NOTE: Dell PC Restore by Symantec and Dell Factory Image Restore may not be available in certain countries or on certain computers. |
Use Dell PC Restore (Windows XP) or Dell Factory Image Restore (Windows Vista) only as the last method to restore your operating system. These options restore your hard drive to the operating state it was in when you purchased the computer. Any programs or files added since you received your computer—including data files—are permanently deleted from the hard drive. Data files include documents, spreadsheets, e-mail messages, digital photos, music files, and so on. If possible, back up all data before using PC Restore or Factory Image Restore.
Using PC Restore:
During the boot process, a blue bar with www.dell.com appears at the top of the screen.
If you do not press <Ctrl><F11> in time, let the computer finish starting, and then restart the computer again.
|
|
NOTICE: If you do not want to proceed with PC Restore, click Reboot. |
The restore process takes approximately 6 to 10 minutes to complete.
|
|
NOTE: Do not manually shut down the computer. Click Finish and let the computer completely reboot. |
The computer restarts. Because the computer is restored to its original operating state, the screens that appear, such as the End User License Agreement, are the same ones that appeared the first time the computer was turned on.
The System Restore screen appears and the computer restarts.
|
|
NOTICE: Removing Dell PC Restore from the hard drive permanently deletes the PC Restore utility from your computer. After you have removed Dell PC Restore, you will not be able to use it to restore your computer operating system. |
Dell PC Restore enables you to restore your hard drive to the operating state it was in when you purchased your computer. It is recommended that you do not remove PC Restore from your computer, even to gain additional hard-drive space. If you remove PC Restore from the hard drive, you cannot ever recall it, and you will never be able to use PC Restore to return your computer operating system to its original state.
|
|
NOTE: If you do not log on as a local administrator, a message appears stating that you must log on as administrator. Click Quit, and then log on as a local administrator. |
|
|
NOTE: If the partition for PC Restore does not exist on your computer hard drive, a message appears stating that the partition was not found. Click Quit; there is no partition to delete. |
The PC Restore partition is deleted and the newly available disk space is added to the free space allocation on the hard drive.
The System Recovery Options window appears.
|
|
NOTE: Depending upon your configuration, you may need to select Dell Factory Tools, then Dell Factory Image Restore. |
The Dell Factory Image Restore welcome screen appears.
The Confirm Data Deletion screen appears.
|
|
NOTICE: If you do not want to proceed with Factory Image Restore, click Cancel. |
The restore process begins and may take five or more minutes to complete. A message appears when the operating system and factory-installed applications have been restored to factory condition.
If you are considering reinstalling the Windows operating system to correct a problem with a newly installed driver, first try using Windows Device Driver Rollback (see Using Windows Device Driver Rollback). If Device Driver Rollback does not resolve the problem, then use System Restore to return your operating system to the operating state it was in before you installed the new device driver (see Using Microsoft Windows System Restore).
|
|
NOTICE: Before performing the installation, back up all data files on your primary hard drive. For conventional hard drive configurations, the primary hard drive is the first drive detected by the computer. |
To reinstall Windows, you need the following items:
|
|
NOTE: Your Drivers and Utilities media contains drivers that were installed during assembly of the computer. Use your Drivers and Utilities media to load any required drivers, including the drivers required if your computer has a RAID controller. |
The reinstallation process can take 1 to 2 hours to complete. After you reinstall the operating system, you must also reinstall the device drivers, virus protection program, and other software.
|
|
NOTICE: The Operating System media provides options for reinstalling Windows XP. The options can overwrite files and possibly affect programs that are installed on your hard drive. Therefore, do not reinstall Windows XP unless a Dell technical support representative instructs you to do so. |
