The information in this article applies to:


 * Microsoft Windows 95

SYMPTOMS
When you run the Add New Hardware Wizard to detect a video adapter, you receive the following error message:

You are using other hardware that conflicts with the hardware you are trying to install.

You have two choices: You can continue or exit.

To continue installing the software, click Next. The hardware will not work properly until you resolve the conflict. If you choose to continue, Windows will provide a troubleshooting tool to help you resolve the conflict when you finish the wizard.

To exit without installing the software, click Cancel.

Device Manager shows a conflict with the standard VGA driver and the new video card that has been detected.

CAUSE
Most video cards are compatible with the standard VGA driver. When you run the Add New Hardware Wizard, you are telling Windows 95 that you have changed hardware when, in actuality, you have not. Therefore, both the standard VGA driver and the new video driver try to initialize the same adapter.

RESOLUTION
When you change the display driver, use the Change Display Type option in Display properties. To do so, follow these steps:


 * 1) Click the Start button, point to Settings, then click Control Panel.
 * 2) Double-click the Display icon.
 * 3) Click the Settings tab.
 * 4) Click the Change Display Type button.
 * 5) In the Adapter Type section, click the Change button.
 * 6) If the video adapter that is installed in your computer is displayed, click it. If it is not, click the Show All Devices option button, click the manufacturer of the video card, then click the correct model.

This procedure replaces the standard VGA adapter with the adapter you choose and does not result in a resource conflict.

MORE INFORMATION
You should run the Add New Hardware Wizard only when you change the physical video adapter, not when you want to change the video driver.
