   The steps are as follows:

1. First, click the Start button and enter "DxDiag" in the search box.

2, will search out a lot of things, no matter, just open the top of the "Dxdiag.exe" this program on the line.

3, DxDiag's Chinese name is called the DirectX Diagnostics Tool, opens after the interface following diagram:

4, at this time we click on the main interface "display" tab (as shown in the red circle above), you can see about the system all the graphics-related content (the following figure):

5, Normal, the following "DirectX function" box in the DirectDraw acceleration, Direct3D Acceleration, AGP Texture acceleration should be "enabled" state, then your computer display system no problem, play a large game, with CAD software, etc., should be normal use.

6, but some people's DirectX acceleration function is not available, how to repair it? Determine if your graphics driver is working properly.

7. Notice the part of the red box? This will show you whether your graphics driver is working properly. The first picture is a video card drive the normal system screenshot, the second picture is a video card driver has the problem system screenshot. Through the contrast between the two graphs, you are actually very good to see what kind of call normal, what is called abnormal. In order to be rigorous, I still have a brief introduction to each parameter in the drive.

8, parameters in the main program driver will be written in the driver file name, if it is written a lot of file names (such as Nvd3dumx.dll,nvwgf2umx.dll, and so on, different video card brands here will not be the same file name, this does not matter), is the normal state, if only to write VGA, Then 100% is a problem with the graphics driver.

9, the following is version information, if it is starting with 6.1.7600, then there is a problem with the graphics driver, if the other is the graphics driver is normal. In fact, this 6.1.7600 refers to the version number of Windows 7, the system can only use its own version number filled in this, said that the obvious card driver is missing.

Next is the date, if it is 2009/7/14 7:25:51, then there is a problem with the graphics driver, if it is the other is the graphics driver is normal. In fact, this 2009/7/14 7:25:51 refers to the time that Windows 7 system compilation was completed.

Then is the WHQL signature, this signature does not matter, whether or not all will not affect the use.

Then the DDI version, where there is information, whether 10, 11 or 12, is normal, if the display is unknown, the graphics driver is a problem.

Finally is the driver model, here is also, as long as there is information is normal, the display is unknown is the graphics driver has problems.

Through the above series of judgments, you will know your graphics driver status, if your graphics driver is normal, please skip to step two, if the video card driver has problems, you need to install the graphics driver.

10, if you are more powerful, know your video card is what type, then you can directly to the graphics card to download the latest driver, and then install and restart it. If you are small white, completely do not know what the video card is exactly what type, you can go to the next Drive wizard, drive home or 360 driving master programs, so that the program directly to help you put the graphics card driver installed, restart the computer can.
