Video Card Configuration Troubleshooting Guide

Issue:

You want to determine whether the stability issues your AutoCAD® vertical product is experiencing are due to your system's video card or the drivers associated with it.

Solution:

First, ensure that your Windows® operating system is up to date. For instructions on updating you operating system, refer to solution TS1069997.

Repair the installation of the product by following these steps:

  1. Exit the product.
  2. Click Start menu (Windows) > Settings > Control Panel.
  3. Double-click Add or Remove Programs.
  4. Select the product and click Change/Remove.
  5. Select the Reinstall or Repair option.
  6. Select Repair my <product_name> and then click Next.

Update your Autodesk product with the most recent service pack and all hotfixes that have been published since the last service pack was released (or that explicitly are described as a post-service pack hotfix). Follow these steps:

  1. Go to the http://www.autodesk.com website.
  2. Click the Services & Support link.
  3. Under Product Support, select the product that you want to check for updates.
  4. Click the Data & Downloads link.
  5. Click the Updates & Service Packs link.
  6. Locate your product version and install all the appropriate updates or service packs to update your product.
  7. Restart your computer.

If there is no improvement in stability after applying these service packs and hotfixes, refer to the following website for a list of the recommended cards and drivers for AutoCAD® products to determine if your video graphics hardware is compatible:

http://www.autodesk.com/autocad-graphicscard

This list is updated to reflect the results of Autodesk Quality Assurance tests. You should always download the recommended drivers directly from this list, as this is the exact configuration tested by Autodesk.

If the same issues persist, disable hardware acceleration for the video card:

For 2006 AutoCAD-based products and earlier versions

  1. Click Format menu > Options.
  2. Click the System tab.
  3. Under Current 3D Graphics Display, click Properties.
  4. Under Acceleration, select Software.
  5. Click Apply & Close.
  6. Click OK.
  7. Restart the application.

For 2007 AutoCAD-based products and later versions

  1. On the command line, enter 3dconfig.
  2. Click Manual Tune.
  3. Clear the Enable Hardware Acceleration check box.
  4. Click OK to close each dialog box.
  5. Restart the application.

If the stability issues are still occurring (especially during startup), you can limit the interaction that the product has with the video card during startup to avoid these issues.

Note: The following procedure can only be performed on AutoCAD 2007-based products or later versions.

For example, to modify Architectural Desktop 2007 in this manner

  1. Create a copy of the shortcut icon used to start Architectural Desktop 2007.
  2. Select the icon, and then right-click it. On the shortcut menu, click Properties.
  3. The following string will be in the Target box:

    "C:\Program Files\Autodesk Architectural Desktop 2007\acad.exe" /ld "C:\Program Files\Autodesk Architectural Desktop 2007\AecBase50.dbx" /p "Architectural Desktop - Imperial"
     
  4. Move to the end of this string and add the following with a space in front of the “/”:

    /nohardware

    The full entry will now read as follows:

    "C:\Program Files\Autodesk Architectural Desktop 2007\acad.exe" /ld "C:\Program Files\Autodesk Architectural Desktop 2007\AecBase50.dbx" /p "Architectural Desktop - Imperial" /nohardware

    Note: These file paths are based on the default installation path of the specified product. You will need to modify them if you chose to install to a custom location or are modifying a different product.

If the stability issues persist, start Windows in Diagnostic mode to determine whether other applications are interfering with the AutoCAD-based product. To run Windows in Diagnostic mode, follow the instructions in solution TS1054234.

If the product ran without issue in Diagnostic mode, then the configuration of Windows (including the configuration of the personal OS system or other programs loaded onto it) may be causing conflict with the AutoCAD-based product.

If running the application in Diagnostic mode did not resolve the issue, then you may be experiencing a hardware or operating system issue, and you should consider performing a clean installation of Windows®. To ensure a clean installation of Windows, install Windows directly from the original installation media provided by Microsoft. Avoid using any OEM (Original Equipment Manufacturer) customized installations or recovery images that may have come with your computer. After you have reinstalled Windows, apply all of the current updates available from http://www.windowsupdate.com.

Install the Autodesk product and the recommended video drivers onto the clean installation of Windows, but do not install any other software. If the Autodesk product continues to experience stability issues, then it is likely that your computer's hardware is causing the problems.
