Windows 7: Sapphire Raedon AMD GPU not detected by Asus MoBo (win7 64)

Sapphire Raedon AMD GPU not detected by Asus MoBo (win7 64)

As the title says my Sapphire Raedon HD 6970 (AMD) GPU is not detected by my Asus M4A78LT-M LE motherboard. This would be simply a problem with the pci port or faulty hardware normally from most of the posts i have read.

However, as I do not have a VGA cable to test the inbuilt graphics card, I connected through the HDMI port on the GPU to my screen, when I get into the windows device manager it is saying that the GPU is non existant, and the screen performance is choppy, I have updated the GPU drivers and the BIOS, I honestly have come to a dead end here, any assistance at all would be helpful, thanks.

PS. this is a fresh build, fresh hard drive with win7/64 8GB ram + AMD Phenom II x6 CPU

I have to ask - did you set the BIOS to use the PCI slot first instead of the onboard video?

Hi Grift and welcome to Seven forums

If it's running through the hdmi from the card then it must be recognised in some way?

What doe's it show in device manager for displays exactly?

Cheers

Paul.

@Gewb Yes, there were 3 PCI options, none of them changed the outcome from the current one.

@Paulpicks21 Display Adapters/Standard VGA Graphics Adapter - only display item here, yet I am only using the HDMI port. I know what you mean though, if it is being detected by the motherboard, then why is it not choosing to run the display with the GPU power, not the onboard one.

Isn't there a setting in the BIOS to turn off the on board video?

There does not appear to be any indication that I can do this within the BIOS or in the manual, the only options are to set the primary display to one of 3x PCI slots (which I have tried) or to the onboard graphics.

Just trying to work out what's what.

So when you fired up the new rig I assume you got no display at all? Then you switched from dvi to hdmi and you got display?

Nope, fired the rig up with HDMI cable plugged into the GPU, got display immediatley through this screen.

Have you tried uninstalling the only onboard display drivers from device manager? It should not hurt as windows will reinstall any missing drivers as soon as it boots up.

Just tried this paul, and post deletion the Display adapters drop down was empty, the screen was still on.

Standard restart from windows, straight into device manager, same "Standard VGA Graphics Adapter" there.
