Updating the graphics card driver
To update the graphics driver, follow these steps:
In Windows, click Start.
Type "Device Manager" to search for the program, and press Enter or click on it.
Note: Although the search box doesn't immediately appear, when you start typing it will begin a search. You may also use the search box on the Task Bar, if this is still available for you.
Expand Display adapters:
Double-click the graphics card.
Click the "Driver" tab.
Make note of the video card model and the date of the driver.
Note: Dates are easier for determining an older or newer driver instead of using the version number.
Right-click on the graphics card > Update Driver.
If Update Driver is dimmed, download and install the latest driver from the manufacturer's website:
NOTE: If updating does not resolve the issue, verify the computer processor and graphics card meet Recommended requirements for your product version (see System requirements for AutoCAD). If it does, make note of the video card model and the date of the driver. Contact the graphics card vendor as the card is faulty.
