Troubleshooting Video Cards
This page will provide some common sense solutions to video card problems.

Q1: I have encountered a problem installing the AGP video graphics adapter with a Socket 7 motherboard. How can I resolve the problem?

When using an AGP / VGA video system with a Socket 7 motherboard ensure that you are using the latest drivers available for your motherboard.


Q2:How do I update my version of Windows® 95 to Support AGP Standards?

The Windows 95A (or OSR1) environment does not support AGP boards.  You will need to update your operating system to Windows 95B or higher.

If your environment is Windows® 95B or C, you have to install the Microsoft Windows® USB supplement so the operating system can properly indentify and control AGP functions in the computer.

To make sure the USB supplement is installed follow the instructions outlined below:

  1. Left click on the Start button.

  2. Left click Settings.

  3. Left click the Control Panel link on the Start menu.

  4. Double left click the Add/Remove Programs icon .

  5. The USB supplement should be listed among the installed programs.

  6. To install the USB supplement, please insert your Windows® 95 CD-ROM in your drive.

  7. If you have Windows® 95B, left click the Start button and left click the Run command.

  8. Input the following command into the run dialog box:

    d:\other\usb\usbsupp.exe

  9. If you have Windows® 95C, in the run dialog box enter the command

    d:\other\usb\usbsup1.exe.

  10. If you have Windows® 98 or higher, the AGP slot will work correctly without adding this patch.

Q3: My system hangs or I get a blank screen when I power on my computer?
  1. Make sure your VGA card is properly inserted into the slot.  Remove and re-insert the card.

  2. Check to ensure the monitor output connector is securely connected with VGA connector.

  3. Clean the golden fingers of the card with an eraser and plug it back to the slot again.

Q4: What if there there are only 16 colors available after I've installed the device drivers?
  1. You will need to install the Windows USB supplement. 

  2. Please upgrade your Windows 95® to Windows® 95B or higher.

  3. For Windows® NT 4.0 you need SP3 or SP4 upgrade which is the requirement for running AGP VGA.

  4. If the system did not upgrade or install properly, the following messages will appear:

    • The computer will ask to install the device driver again.

    • The video system still can only support 16 colors.

    • The system will show your driver is not ready or otherwise indicate the problem is still there.
  5. If your system has a motherboard with a VIA, ALI, or SiS based chipset, you have to install AGP.VXD¡¨; otherwise, your system will not function properly.

    You can get a .vxd driver from your motherboard manufacturer. 

  6. If both USB and .vxd drivers are installed, be sure that the VGA driver has also been installed correctly.
