Windows 7: PCI/Integrated Graphics Problem

I have an Asus Pundit-R that is working pretty well with Windows 7 apart form the poor performance of the inbuilt ATI Radeon 9100IGP graphics. To try to improve on this I have added a Powercolor HD2400 Pro in one of the PCI slots.

Unfortunately, there is no BIOS option to disable the onboard graphics adaptor - even when the BIOS is set to use the PCI card it remains enabled. I therefore see two display adaptors in Device Manager; the onboard one ('Standard VGA Graphics Adaptor' and the HD2400 ('ATI Radeon 2400 Series'). The onboard graphics are running with the Windows 7 vgapnp.sys driver and the HD2400 with the latest AMD Catalyst drivers (8.661.0.0) and everything looks good.

However, Windows 7 then uses the onboard graphics as its primary interface (as expected) and I can't get any output on the HD2400. Only one monitor shows up in 'Display... Screen Resolution' and pressing the 'Detect' button fails to add the second display. What I want to do is to get the second display running and then set Windows to use that one exclusively.

This could be the expected behaviour if vgapnp.sys wasn't a WDDM-compliant driver, but surely it must be...?

Any ideas about how I can get the HD2400 working?

Dude I'm having this SAME problem with my GeForce 9400 GT! I even made a video of it to show people: [ame="http://www.youtube.com/watch?v=KeyZRk8k-tc"]YouTube- Graphic Card Display Not Detected[/ame]

lol I know exactly watcha going through. But I was told to disable my onboard graphics, so I'm gonna try that. I'll tell you how it goes...

I can't disable the integrated graphics - there's no BIOS option for that (and yes, I have got the latest BIOS!).

All I can do is change the priority between Integrated first and PCI second and PCI first and Integrated second. If I have Integrated first then I get the problems I described in the earlier post. If I have PCI first then it's worse - Windows comes up on the HD2400 but there is a Code 12 error (This device cannot find enough free resources that it can use) on one of the PCI-to-PCI Bridges and the HD2400 shows up as a 'Standard VGA Graphics Adaptor' with a Code 10 error (This device cannot start).

Device manager. Right click on the other device (not ATI one) under display adapters. Choose disable. Reboot.

Thanks for the response. I've tried out your suggestion, and Windows still comes up on the integrated adaptor (yes, that's the one that is supposed to be disabled and which now has a black down arrow against it in Device Manager!). There's no output on the HD2400.

Plug your monitor into HD 2400.

Update your bios and disable all unused ports. (Serial or Parallel, floppy etc...) Put PCI as initial display device or similar.

Then see about getting latest chipset driver from manufacturer's website.

Then install latest ATI driver from website. If you can't do this part, let me know after you did the other stuff.

The BIOS is the latest version. I've disabled every onboard interface except for the USB ports and LAN, but still get the Code 10 and 12 errors when the PCI adaptor comes first (but no errors at all when it comes second).

There's nothing on the Asus web site for any OS after Windows XP. I got the LAN driver working first, using an old version of Catalyst. After that all of the rest of drivers installed themselves from Windows Update and the the LAN driver updated itself, so they should all be as current as possible.

I did a complete driver uninstall, rebooted and then reinstalled the latest Catalyst Windows 7 32-bit drivers from ATI. The log is below.

Error messagesThe system is still behaving exactly as before - the HD2400 is driving the Windows display but shows up in Device Manager as a Standard VGA Graphics Adaptor with a Code 10 error.

Post a screenshot of device manager with system devices maximized. Another for display adapters maximized.

Also, "system information" from start menu search box. When it opens, ctrl+s.
Use Winrar on the saved file and then attach .rar to post with screenshots.

Also, physically install the PCI card to another slot furthest away from where it is now. Switch it with another if there are no empty slots available.

ASUS P4R8L this is your mobo and it would seem that there is no support (drivers) beyond XP...
