My ASUS K42J dual graphics card switching issue.

Symptom: The graphics card cannot be automatically switched to the independent graphics card when playing games. Solution:

Update nvidia graphics driver, version number (2 graphics drivers can be updated at the same time to solve the problem) win732-bit: nvidia display driver:

Display drivers.

bit under the NVIDIA display driver.

Intel Display Driver.

The reason is very simple, no matter how you set it, you can't escape the fate of being stuck when you play games because the graphics card is switched there.

1. First of all, you need to confirm the ASUS K42D machine model, as well as its firmware version, so that you can choose the right graphics card. 2. According to your model and firmware version, you need to consider the core frequency, video memory capacity, and interface type of the graphics card. 3. Install the new graphics card into the chassis.

4. Connect the graphics card to the SATA port in the chassis and replace the power cable. 5. Install a new graphics card driver program, which can be obtained from regular channels, and after the installation is completed, you need to restart the computer to make the new graphics card take effect. 6. Check whether the new graphics card is working normally, you can use the diagnostic tools that come with the system to detect it, or you can install some hardware detection software to check whether the relevant parameters of the graphics card are normal.

Haha,I've had the same problem as you.,My book is ASUS A40J.,It's a dual graphics card like you.。

The solution is very simple,First of all, the dual graphics card switch must be under the win7 operating system,If you use XP or 2003,It will not switch to the independent graphics card,You can only use the integrated graphics card。

If you are using Win7, it is easy to do, look at the lower right corner of the Win7 desktop, find the ASUS NVIDIA control panel (click on the small triangle in the toolbar in the lower right corner to see), open the left "Manage 3D Settings", and select "Program Settings" on the right side. Haha what do you see? There are two options:

1. Select the program you want to define. (Select your game here, and use the Add button next to it if the list doesn't already exist). 2. Choose the preferred graphics processor for this program (this is to let you choose the graphics card, there are three options, 1 default, 2 choose the integrated graphics card, 3 choose the high-performance NVDIA processor, and the third item is the discrete graphics card!)

After selection, click "Apply" in the lower right corner and restart your computer.

But note,Originally, this function should be automatically switched,If you need to switch manually,It means that your graphics card driver is installed a little bit wrong (judging from the symptoms,Your system may have been installed by a merchant who sells computers with ghost,Right?) ),If you can solve it according to my tutorial, of course, it's all right.,If you can't solve it.,Go to ASUS official**The next latest graphics card driver,Note that the driver model should match your book.。

Finally, let me tell you,ASUS's A4 series book is very strong! I've just cleared the five-year-old game.,All the indicators of the graphics card test are A.,So please rest assured.,At least most games before 2010 it didn't have any problems at all.。

Hehe, I wish you a good time with your little Ben and be nice to it.

By the way, disdain upstairs, what "blocker" ?! If you don't understand, don't mislead, there are only program conflicts, no program blocking, and even if you block it, it's antivirus software or firewall that prevents Trojans and viruses from running. What kind of virus is driver switching? Pure nonsense!

Uninstall the independent graphics driver,Reinstall the driver,I'm also an ASUS notebook,When the dual graphics card fails,That's how I solved it!

It is possible that there is a blocker in the game.

Hello, dear ASUS users.

When the system processes a large number of traffic tasks, it will automatically switch to a discrete graphics card. When the task volume is not large, the system automatically switches to the integrated graphics card, but you can also choose to use the discrete graphics card all the time, and the operation steps are as follows:

1. Right-click on the desktop and select NVIDIA Control Panel on the pop-up menu.

2.Then pop up the NVIDIA settings menu, select Manage 3D settings, you will see the option to use the integrated graphics or independent graphics card globally, after selecting the discrete graphics card, the system will use the graphics card you selected when performing tasks.

There should be a performance or energy-saving option in the control panel, energy-saving is built-in, and high-performance is independent.

Sympathy, I tossed for a few days, installed the system twice, and finally figured it out.

1、Of course, you have to install the win7 system.,32-bit,64-bit I didn't test.。

2. Go to the official website of ASUS.

It should be a system issue. If it's win7, it will be automatically switched, and if it's xp, it won't be switched automatically.

Be able to understand what you mean, the situation is like this.

The video memory of this notebook is1G,Theoretically, it is enough to drive the Dragon Babu,And this graphics card due to the use of dual graphics cards,It will allocate 128 of the system memory to the integrated display,In fact, there is no such problem。

Of course, the best solution is to change the system, I tried this solution, and the discrete graphics card can also be used, but it takes time to activate it when entering the game, and it is automatic. After changing the XP,There will be no network card driver,This network card driver can use win7's network card driver,There is an installation disc,You need to manually find this。 Test this plan for yourself!

I have the driver for this graphics card here, you give me an email and I will send it to you.

The driver of the graphics card should be installed, the notebook driver should be installed, and the default is generally to use the integrated graphics to work, when the amount of data to be processed is large, it will be switched to the independent graphics card, and the following describes the operation steps for manually switching from the two graphics cards to the independent graphics card:

Discrete graphics card is AMD discrete graphics card (A card) to set up a dual graphics card to switch to discrete graphics card: in the blank space of the computer desktop, right-click the mouse button, a small menu will pop up, and click "Configure interchangeable graphics card" in the options, as shown below;

Then in the AMD switchable graphics card settings that pop up, add the applications that need to be set to run on a discrete graphics card, then select "High Performance", and click "Save" at the bottom when you are done, as shown below.
