PC won't detect new graphics card

486 264 August 11, 2019 at 05:43 AM
I'm trying to install a new graphics card in my HP SFF PC model S5120Y and cannot get the PC to detect a dedicated graphics card in the PCI x16 slot. Only integrated video works through the VGA port in the back of the PC.

The card does not show up in Device Manager and I have tried two different graphics cards. I have changed the primary video adapter to PCIx16 in the BIOS and checked the BIOS is the newest version.

Any suggestions on disabling the onboard video (Nforce 430 chipset GeForce 6150SE) completely?

whats the card,some cards with micron memory don't work new
I tried an AMD 8490 low profile, then GeForce 9600 GSO (with larger power supply) and neither would work.

There's a setting in the BIOS/UEFI that you have to change.

I think there has to be a setting to change in the BIOS, but the only setting that seems relevant is Primary Video Adapter and I have changed it from onboard to PCIEx16.

The AMD 8490 does not need external power, but the 9600 GSO was plugged into the 6 pin connector when I tested it. I can try running Windows update, but I already installed the latest AMD drivers (for the AMD card). Catalyst Control Center says something like drivers not found (because the card isn't detected in Windows) when I try adjusting graphics settings.

I'm starting to think maybe the card (or any modern graphics card) is simply not compatible with the motherboard. This site: https://forums.tomshardware.com/t...ed.744749/ says some HP motherboards cannot supply enough power through the lane (never heard of that issue before).

The BIOS setting is for video adapter priority, and does not allow for disabling onboard video entirely. I can set it to PCI, PCIEx1, and it won't matter if I don't have a card installed in the other slots.

Try updating the firmware on the hp.

Before we perform any OS deployment, the box gets it's Firmware updated 1st.
Functionality and Security are why we patch the FW.

Are you referring to the BIOS? I updated the BIOS to the newest version back in 2012 and it says 5.38, although the website says the newest BIOS is version 5.49. However, this site says the BIOS id 5.38 refers to update 5.49: https://www.wimsbios.com/biosupda...lionS5120Y .

Regardless, I tried running the BIOS update: https://support.hp.com/us-en/driv...el/3970033 but the executable won't continue because it does not detect Windows Vista since I have updated to Windows 7.

This computer is REALLY old and it was underwhelming 10 years ago. Honestly you probably shouldn't waste your time on it. You'd be much better off with a newer refurb.

There are different versions of PCI-E. This machine is old enough I wouldn't be surprised if this is the source of your issues. That BIOS update you can't install might even adderss pci-e issues.

Yes, this would include the BIOS as part of the updates I was referring to.

I have to agree that this is due to age. nForce 430 is 15 years old. You could conceivably Google for best GPU 2004 and watch for one on ebay. You will most likely need that bigger power supply and should stick to Nvidia. I'm not sure what your goal is, but any video card compatible with your PC isn't likely to run any games released in the past decade.
