Problems caused by new graphics card

June 9, 2009 at 10:20:43
Specs: Windows Vista
I have a gateway GT5676 that came with a ATI Radeon HD 3200 Graphics card merged into the motherboard. I bought a NVIDIA GeForce 8400 GS to try and improve my graphics, but it just caused a bunch of error messages to appear like 'incompatible graphics adapter' and such, apparently these two brands don't work well together. The problem seems to be that the ATI card is still running and screwing everything up. I tried to disable it, and even to uninstall it all together, but everytime I try to do that, the ATI card just reinstalls itself. This computer used to be incredibly fast, but now I can't any sort of video whatsoever. It would be awesome if anyone could help me out. Thanks so much.

Put the ATI card back in and uninstall from device manager (devmgmt.msc). reboot. Use drive cleaner to rid yourself of all your old ATI drivers in safemode. reboot. Install new card and install new drivers. Computer doesnt know what to do with this new card.

Why did you buy a PCI graphics card. Your motherboard has integrated PCI-e graphics with an available PCI-e -16 slot to add in an upgrade card.

PCI is TWO generations behind PCI-e. AGP came in between.

The card you bought can run at the same time as the integrated graphics. That is why you are having problems.

I suggest you return the PCI card and get a PCI-e based card.

PCI and PCI-e are totally different technology.

You may also have to go into the BIOS and disable the onboard graphics, or at least have the PCI-E slot initialize first.

The NVIDIA card is a PCI e card, at least that's what it said and that's where it is on my motherboard. I'll try to uninstall the ATI card again and then use a driver cleaner, I didn't think about that. Hopefully that will work, thank you!

okay, I just tried to uninstall the ATI card and then reboot in safe mode then try to remove all of the ATI programs. I uninstalled the ATI card in the device manager and rebooted into safe mode, and found that the card had once again reinstalled itself. So, I uninstalled it again, but this time I was in safe mode. Oh and I couldn't find the drive cleaner option in safe mode, I have no idea how to do that. Anyways, when I rebooted normally, my computer doesn't recognize the ATI card, it now says 'Standard VGA graphics Adapter'. This thing installed itself onto my computer and now it's not working, and now my computer seems even slower. What did I do and how do I fix it?

Sorry about the PCI card thing. The first reference I found for that model said it was a PCI card.

Possibly a dumb question but you do have the monitor connected to GeForce card?

What you need to now do is UPDATE the drivers for the nVidia GeForce card (8400). Go to Device Manager and expand the listing for display adapters. Then right click on the listing for the Geforce 8400. Choose udpate driver. Choose No, not this time> Next> Install from a specific location> Next. Then Browse to the correct location of the drivers. Then follow the prompts.

To be honest, I have no idea what card my monitor is connected to. How is one able to check that sort of thing?

I did exactly as you said and went into device manager to update my drivers, my computer asked how I wanted to search for driver software and I selected the 'search automatically for updated driver software' which is both from my computer and on the internet. When I did this, it said my drivers were all up to date. So..... haha.
