Hi Wayne, it's rule of thumb to always uninstall the old software from add/remove programs before installing the newer software drivers. The reason for this uninstall is so the two programs do not over-write files with the same name.
The ASUS P4S800-MX motherboard does have an onboard graphics card, (SiS Real256E). If you added another video card into the AGP slot & did not disable the onboard graphics, than you're AGP card will not run correctly. (I'm suprised it even loaded)!
Please read page 2-19 in you're motherboard manual to help fine tune the bios when using an AGP video card. Than go to page 2-21 & than set, Primary VGA bios to; [AGP,VGA Card]. Save & exit. The PC will restart.
Press & hold the power on button on the case. This will power off the system. Unplug the power cord from the power supply. Insert you're AGP card & make sure it is fully seated. Close the case & plug in the power cord. Boot up the system. Uninstall any other software you did install for the AGP card. Retsart the PC after uninstall is complete. Install the latest software you downloaded for the AGP card. Restart after install is complete.
Lastly, run windows update service & choose ustom, not express. Check for hardware & software updates. You're system should function much better & when you check the system properties you will find you have more system memory. This is because the onboard video used you're system memory to run.

Good luck Wayne!

How do i update my pixel shader for my computer to play games ?

Hi Gerry, if your HP's video card is capable of running the game, you can update the video driver. I would suggest trying the HP Driver Download Support website first. Here's the link: Drivers Downloads.

If your video card is not capable of running the game, you will want to look into a different video card.

Hope that helps you out! :)

How do I update my video card driver?

First of all you need to know what video card you have. If you have Windows and I assume you do go to Start > Control Panel (switch to classic view) > System click on Device Manager and in the list find 'Display Adapter'. The name of the driver appears. Make a note of it. Go directly to the website of your driver's manufacturer. Follow the instructions to download and install the right driver. Restart your computer to let it take effect.

Warning: this is the manual way to update. If you are not a tech guy, attempting to change video drivers could make your computer inoperable or cause severe problems. As a result, you can rely on a drive detective software to help fix the driver issue automatically & accurately.

This way also saves you time & energy.

Farm simulator loads but lags badly about 5 min. into the game. It then freezes.

That sounds like a problem with your video card driver. Make sure you have the most up-to-date drivers for your system.

There are two ways to do this, the automatic way (not guaranteed to work) and the manual way.

Automatic way: Right click on My Computer>Properties>Hardware>Device Manager. Locate your video card and right click>properties. This should give you a pop-up window, and on the first tab you should see "Update Driver". This will launch the driver update procedure.

If that doesn't work (the driver update says your drive is up-to-date, or it can't find the driver), take note of the make/model of your video card, and visit the manufacturer's website (IE a nvidia card would be, etc). Go to the support/downloads page and find the driver for your card, download it, install it, then restart your computer.

If neither of those work, check the system requirements for the simulator and make sure you meet or exceed those requirements (exceed is preferable, obviously). Also try going into the options for the simulator and changing your graphics/resolution down a little bit to make it easier on your card.

MY PC dosent have vga compatible drivers and also my games are not starting so what to do to solve this problem

Sounds like the last time your a new operating system was put on your computer, the video card did not get drivers. For vga, Windows will use generic drivers if possible. Usually Windows recognizes video cards and installs the drivers. Occasionally, Windows does not recognize the video card, and you must do it yourself. Look up your laptop model online, and search for video drivers. Your best bet is from the manufacturer, or from Windows update, as you cannot always trust downloads from other sources. Depending on where you find the driver, and how it is packaged, you may have to either get it as an update, in which case it will install itself, or you may have to download it. I like to make a new folder when I do something like this - such as Jon on the C drive. Once downloaded, run the program and it will update. Make sure you have no other programs running. A reboot migh be needed. Sometimes these may be rather large downloads, so be prepared to wait if you have a slow connection. When done, I like to copy or move the update to a CD or DVD in case I need it later. Your games will not work unless they can tell which video card is installed, and if your computer is using the generic drivers, that is why they won't work.

When playing videos on my computer the video driver fails and the video screen goes green... I get a message saying "video driver failed but has recovered" Happens every time i try to watch a video. I'm...

Most probably the drivers downloaded from Nvidia is not the correct version or an older version for your video card. That is probably windows revert the best options drivers for your video card. You can check the version or the date windows automatically installed from the device manager. You also can also use "Microsoft Updates" to update your drivers.

To remove the video drivers, go to "safemode" and from the "device manager" uninstalled the video drivers.Be sure to download the correct version for you video card and run the installer from Nvidia.

Do update your DirectX too.

Hope it helps.

Visual errors occur and the game is unstable is there a driver update to fix the problem?

I found the driver for your card, though you may want to punch in the specifications yourself.
Go to the link and look on the top right. You'll see "Download Drivers".
This all depends what game you are playing and what system you're running on.
With what little information I had, this was the best I could do.
In my opinion, if you're trying to play a recent game, you'd have to bring the visual settings all the way down in the game.
If this wasn't helpful, post more information please.
Let me know.

Compaq Evo N610c need video driver upgrade

Nevermind, I just looked up the system requirements for Hoyle 2009. The requirements for the computer video card is a minimum of 64MB of Video RAM, which you may not have in the laptop. If you don't have a 64MB+ video card, it won't work. If you do have a 64MB+ video card, but don't have the correct driver installed, you can get the drivers you need by going to Windows Updates and letting Microsoft install it for you.

I'm not sure if I understand clearly, you are having problems getting the driver cd to install?
Try a manual run by inserting the cd then go to Start>Run- then browse for the drive where the cd is located and then select open, you may need to choose install.exe of there isn't a setup.exe option
