PROBLEM WITH AGP PORT & DRIVERS

[visiontech]

I have an alton motherboard A641A, I installed two different kinds of video cards and the computer will only show standard vga graphics. I have tried all the normal things,making sure the card in installed properly, removing and reinstalling drivers. when i go to display properties and look at detail drivers there is nothing there.I removed display device and let windows me find it and loaded drivers from there. nothing seems to work. Please Help!

It may be just confused by all this installing and uninstalling.
Be absolutely sure no display drivers are loaded, delete all display drivers in the control panel, sometimes there can be several loaded at a time, and then shut down to see if it plug and plays. Martin

Thanks for the advice. i tried that and when i rebooted it found the card and automatically loaded the same drivers.and when windows menu screen tries to appear on boot up the screen just goes black but you can see the mouse arrow but windows will not finish loading. I did install a PCI video card and the drivers loaded and i had full 3D accelleration. but when i use AGP is when i have the problem.

I'm guessing that you ran the un-install routine for your video card and read the "Read Me" file for all the tips on installing and un-installing your video card so...
Try this,
Boot in safe mode and go to the device manager. Look at all the video cards (safe mode will show all the cards that are resident in Windows)and delete them all. Now try re-installing your divers...Still no video? Make sure your AGP card is getting an IRQ in the BIOS otherwise it will only run in PCI mode. Also make sure there are no IRQ conflicts when you look at the system properties in the device manager. Lastly make sure you load the most recent AGP chipset driver for your MOBO before you load the drivers for it...oh I forgot, look for a BIOS update your MOBO may have issues with your AGP card that are resolved in the latest BIOS update.
