 * Feezing
 * Printing Problems

 * Colors Do Not Look as Expected
 * Screen Redraw Problems



How to Determine if your Display Driver is Causing a Problem
Windows 95:  Test the problem in Safe Mode. Start Windows 95 in Safe Mode, a diagnostic mode of Windows 95, and attempt to reproduce the problem you are having. To do this:  On the Windows Start menu, click Shut Down. In the Shut Down Windows dialog box, click Restart The Computer. When you see the "Starting Window 95" message, press F8.

NOTE: If you see the Windows 95 splash screen appears, repeat steps a through c. Choose the Safe mode option. Or, if you are running a shared copy of Microsoft Publisher, choose the "Safe mode with network support" option.

Windows 95 will start in Safe Mode, without network support. The words "Safe Mode" appear in all four corners of the screen. Test the problem. If the problem goes away, your video driver may be the cause. When you run Windows in Safe Mode, Windows uses default settings (VGA monitor, no network, Microsoft mouse driver, and the minimum device drivers required to start Windows). Therefore, the problem could be related to any software that extends the functionality of these default settings.

If the problem does not go away, this usually indicates the problem is not related to the video driver or video sub-system. After you finish this procedure, restart your computer and start Windows as you normally do.</li></ol> </li> Change the display driver to VGA. To do this: NOTE: Some display adapters are not compatible with the Windows 95 standard display driver. If you are not sure whether your display adapter is compatible with the VGA display driver, please consult the video adapter manufacturer. <ol style="list-style-type: lower-alpha;"> On the Windows Start menu, point to Settings, and click Control Panel.</li> Double-click the Display icon.</li> Click the Settings tab.</li> Click the Change Display Type button. Write down all information regarding your current adapter. You will need this information when you restore your original settings.</li> Under Adapter Type, click Change. Click Show All Devices.</li> In the Manufacturers box, click Standard Display Types. This option should be at the top of the Manufacturer's list.</li> In the Models box, click Standard Display Adapter (VGA), and then click OK.</li> Click Close.</li> Click Close again. If you are prompted to restart Windows 95, click Yes.</li> Test the problem. If the problem goes away, your problem is related to your video driver or sub-system.</li></ol> </li> : Some display adapters are not compatible with the Windows 95 standard display driver. If you are not sure whether your display adapter is compatible with the VGA display driver, please consult the video adapter manufacturer. Check for any conflicts in Device Manager. In some cases, a hardware conflict may manifest itself as a video problem. <ol style="list-style-type: lower-alpha;"> On the Windows Start menu, point to Settings, and then click Control Panel.</li> Double-click the System icon.</li> Click the Device Manager tab.</li> <li>Look for a problem with any installed device. If there is a problem with a device, you will see one of the following symbols on the device icon: <ul> <li>Black exclamation point (!)</li> <li>Red "X"</li> <li>Blue "i"</li></ul>

NOTE: Some sound cards and video adapters do not report all the resources they are using to Windows 95, and therefore, cause Device Manager to show only one device in conflict, or no conflicts at all. To verify whether this is the case, disable the sound card or use the standard VGA video driver to see if the conflict is resolved. (This is a known problem with S3 video cards and 16-bit Sound Blaster sound cards, or those sound cards using Sound Blaster emulation for Sound Blaster compatibility.)</li></ol> </li></ol>

What to Do if Your Display Driver is Causing a Problem
Windows 95: <ol> <li>Determine if you are running a 32-bit video driver, using these steps: <ol style="list-style-type: lower-alpha;"> <li>On the Windows Start menu, click Run.</li> <li>In the Open box, type system.ini, and then click OK.</li> <li>Locate the display.drv= line in the [boot] section of the System.ini file. If you are using a 32-bit display driver, the display.drv line will look like this:

Display.drv=Pnpdrvr.drv

If the Display.drv line does not look like the one above, you are using a 16-bit display driver. If you running a 16-bit video driver, contact the manufacturer of your video driver and obtain a 32-bit driver designed for Windows 95 (if one is available).

NOTE: Replacing the video driver will not solve the problem if something else is conflicting with the correct operation of the video driver.</li></ol> </li> <li>Modify the Advanced Graphics Settings. <ol style="list-style-type: lower-alpha;"> <li>On the Windows Start menu, point to Settings, and then click Control Panel.</li> <li>Double-click the System icon.</li> <li>Click the Performance tab.</li> <li>Under Advanced Settings, click Graphics.</li> <li>Note the position of the Hardware acceleration slider. Move the slider one position to the left to decrease hardware acceleration.</li> <li>Restart your computer and test the problem again. If the problem does not go away, repeat steps a through e, moving the Hardware Acceleration slider one position to the left until it is set to none.</li></ol> </li> <li>Obtain a different display driver.

Contact your display adapter vendor and obtain an updated Windows 95 display driver.</li> <li>Reinstall your Video Driver.

Reinstall Windows 95 and select the Verify option.</li></ol>

Windows NT:
