Windows 7: Pci-to-Pci Bridge (Error: Code 10) - PCI Video Card

Pci-to-Pci Bridge (Error: Code 10) - PCI Video Card

Before I state my issues I will list what I'm running and what I'm trying to accomplish.

I'm running Windows 7 Enterprise 64-bit edition, not the Beta or RC. I have 3 video cards in my possession (listed below).
- (PCIe) Evga GTX260
- (PCI) Evga 9400GT
- (PCI) Evga Fx5500
Out of those 3 cards I only use the GTX260 and the 9400GT. I had to 'retire' the Fx5500 because the latest WHQL (certified) drivers only provide support as far down as the "6 series" Nvidia cards. Unfortunately the Fx5500 is a "5 series" and falls below that line. I have already tried to use the GTX260 and Fx5500 in previous versions of Windows (XP and Vista), but there is no way to download and install two separate drivers for two of the same make of video card - you'll get nothing but errors. There is the option of going to a place like guru3d.com and downloading a custom supported driver that covers both the GTX260 and Fx5500, but the drivers are not certified and lack support. Therefore, I purchased and now use the 9400GT which is covered under the drivers for the GTX260 and eliminates the need for messing around with custom drivers. Also, the 9400GT has a better graphics processor and more memory than the Fx5500, so it was time to upgrade anyway.

Now that you have some background info here is my issueÖ Whenever I install the 9400GT I get a second 'pci-to-pci bridge' entry (the other entry has no errors) that shows up under 'System Devices' in the Device Manager. The second pci-to-pci bridge entry has a yellow triangle with an exclamation mark on it that refers to a problem. When you check the properties of this device it more or less says that Windows has detected a problem (Error Code 10). The GTX260 still works and even shows up under the 'Display Adapters' as a GTX260, but no entry for the 9400GT exists. I have tried the 9400GT in both PCI slots and each time it does the same thing. If I pull out the GTX260 and ONLY run the 9400GT, I still get the pci-to-pci bridge issue, BUT I do get a picture and can boot into Windows 7 without a hitch. When I do this there is still nothing listed under the 'Display Adapters' as a 9400GT or even a VGA compatible device.

After messing around with this for 10 hours (yes, I said 10 hours) I decided to dig out my retired PCI video card (the Fx5500). When I installed this card I had no 2nd pci-to-pci bridge entry appear under 'System Devices', and the one that was listed had no yellow triangle or error codes. I then checked under 'Display Adapters' and Windows 7 had recognized it as a VGA compatible device and was asking for drivers.

I have now concluded that there is definitely no issue with the motherboard or any of my hardware (including video cards). At first EVGA Support and I had suspected that the motherboard may be bad because of all of the pre-diagnostic steps I had taken during my 10 hour ordeal. I'm not going to list everything I did because it would literally take 3 hours to type it all in. Just believe me when I say that I have tried most things including but not limited to the latest bios updates (flashed 4 times and completely reset to ensure accuracy), custom IRQ management, entire OS re-installation X2, multiple/latest chipset drivers installed, multiple/latest video drivers installed, memtest testing, complete hardware teardown and re-build (adding one device at a time), and MUCH more. The only thing I did not try was installing a different OS other than Windows 7 64-bit to see if I could replicate the issue. This is a waste of time though because letís say that I install Windows XP Pro and the 9400GT doesn't have this issue... Well, that's great, but who gives a damn about XP Pro when I have been using it for the last 9 years and when I have a full version of Windows 7 that I want to use? I'm certainly not going to run XP Pro over Windows 7 just to use this PCI video card. Second, if I install XP Pro and it still gives me the same pci-to-pci bridge error then again, I've only wasted more time because if itís not going to work in either OS then Iím sure as hell not going to leave XP Pro installed when I can use Windows 7.

It's not like I think I have this all figured out 100% either which is why I have posted this thread, but in my opinion it seems as if I only have three outcomes here. Correct me if I am wrong or if you have any additional input because anything would be greatly appreciated, but here is what Iím thinking (see below)...

Option#1 - Buy a third PCI video card (like a 9600GT - or some other series that falls under the driver support for my GTX260) and see if I get the same pci-to-pci bridge error.
Option#2 - Maybe the issue is that EVGA's chipset/motherboard drivers have a problem loading the pci-to-pci bridge driver that this particular 9400GT card needs. If so, then it could be a long time before the issue is recognized and new motherboard drivers are released.
Option#3 - Maybe the issue is that Windows 7 has an issue seeing the pci bus for this card, thus causing the issue. If so, then I would have to wait for Windows 7 updates to come along to address the issue - which could be a VERY long time.

Since I know the card works (tested it in a XP Pro machine and Vista for verification) I can only think that the above three options is all I have left to go on. The fourth option is to only run two monitors on my GTX260 and just forfeit using three monitors all together - this would really suck. I really don't want to spend any more money on "trying" another PCI video card either when I just spent $800 upgrading all of my hardware to run Windows 7. Again, any input is appreciated. I apologize for this long post, but if I did not add details then we would be playing thread tag until Christmas!

Thanks,

Jeepy

Well you could sell all your video cards and get this one Newegg.com - ASUS EAH5870/G/2DIS/1GD5/A Radeon HD 5870 (Cypress XT) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card w/ATI Eyefinity - Desktop Graphics / Video Cards it supports 2 dvi out and 1 hmdi with the proper adapters you could run 3 displays from this 1 card. I know that's not the answer you were looking for.I did a lot of goggleing and it seems like everyone who runs the 3 displays 1pci-e and 1 pci do it in XP it may very be well that at this time it can't be configured properly in win 7. Sorry but I read enough articals my eyes are tired, and they all have to do with XP. Of course except for the new card linked above. Good Luck and welcome to sevenforums.

Thank you for your reply. I appreciate your efforts in 'googling' this problem - as I have completely exhausted myself from searches as well. I did read the article you posted from tomshardware.com. The only problem I have with the cards that support HDMI is that my 26" Sony Bravia does not display the picture quite right because it's more of a TV than a computer monitor. What I mean is that a TV that has HDMI on it is not necessarily geared toward receiving signals from a computer video card. TV HDMI's are more geared towards receiving their signals from DVD players, entertainment system equipment, etc... That’s not to say that it won’t work with a video card, but the quality of the picture when used on a regular TV is not near as great as a product that was built with being ‘primarily’ used as a PC monitor and TV in mind. My current video card (GTX260) supports HMDI and so have my other two previous video cards, but the picture looks like %$@! because of how the TV interoperates the signal from the video card. It's not unbearable to use, but cannot compare to a DVI or even a VGA signal - which my TV in-fact does have a VGA-input and using that with my video card blows away hooking it up via the HDMI.

Also, I'm not using (two) pci-e cards - just one. I'm running 'ONE' GTX260 pci-e and 'ONE' 9400GT pci video card. I saw in your post that you had referred to this situation when using (two) pci-e cards and (one) pci card - which I am not. Maybe a typo or misunderstanding, but I wanted to make note on that for confirmation.

Thanks again for your reply! It's not what I'm looking for, but I appreciate you taking the time to read this and give some feedback. As you noted too, Windows 7 may just not be able to do this with this specific Nvidia GeForce video card yet. I may have to just lay down the money on another PCI video card to see if I can get it to recognize since it can recognize my Fx5500. Maybe there’s just something about the 9400GT and how it was manufactured that Windows 7 can’t deal with…? Maybe it’s just the way EVGA manufactured the 9400GT and a 9400GT from XFX or ASUS would work…? Who knows… Anyone else have any input?

Win 7
 
 

I'm having VERY similar symptoms in my conversion to Win 7 64-bit from XP Pro. I have an on-board Intel "card" and a Radeon 7200 PCI card (ok, not as sexy as sexyjeep's setup, but it still causes same problem ). I've gotten the internal card to work fine with an updated driver, but no matter what I've tried I can't get the Radeon adapter to be recognized as anything other than "Standard VGA adapter", and no monitor device appears. I've tried to "force" a Radeon driver with Have Disk, but this has resulted in the Error 10.

Also the same - if I change which adapter is primary in the BIOS, it will boot Win 7 with the Radeon using a Standard VGA driver (yuck), but will not recognize the internal card nor use it.

Lastly, my Win 7 is actually booting directly from a VHD so I still have my old XP install as an option on boot, and the display still works fine in XP so again, no motherboard or hardware issues here.

Were you able to get anywhere with your issue? I'm to the point of looking for a PCI-e or AGP replacement for this card, but would love to know if you found anything else related to this. Thanks!

You might want to have a look at this post I made awhile back at the EVGA forums.
EVGA Forums

Going from your symptoms I can only guess this may be what the problem is.

This is mostly a pci conflict specifically with the EVGA 780i and 790i FTW boards.

You can also do the registry change manually but the .exe in the post I linked too does this for you.

The zip file makes a small change to the registry which allows Windows to see the card as a non pci bridge.

After restarting your machine Windows should be able to see your second card. I'm only guessing you want to use the card as a physics card.
You may need to install the .exe twice and restart twice.

I'm not sure if it will work for you but it's worked for Asus sound cards and Nvidia grapics cards on 780i and 790i FTW boards.

I was not able to get anywhere with mine sspenser. I actually just gave up on it and was looking into the new Radeon card that supports Tripple digital out and ditch the whole PCI video card concept all-together.

I was interested in checking out the link that chev65 posted, but the link does not work. Could you please re-post it?

Thanks!

Hi, that link for the zip file containing the fix is no longer valid. Can you please re-post the link or add the file to this post so that I can try it out?

Thanks,

Quadro FX 3450/4000 and GeForce 8400 GS

Yes, Please if you could provide additional details as to how we could fix this. When I install my second graphics card it shows up as a PCI bridge in BIOS. How can I get it to be detected as a video card?

I have a Quadro FX 3450/4000 installed and working fine.
I want to install my GeForce 8400 GS into the PCI slot, but when I do the system recognizes it as PCI Bridge in BIOS. Ive tried another PCI graphics card, an ATI Radeon 9000 128 mb, and it is recognized as VGA, as is teh Quadro, and in device manager it comes up as vga adapter, but because its so outdated there are no drivers for it.

Please Help!!!

Windows 7 Professional 64-bit
 
 

I am experiencing this same exact issue. I am runnning a 9800GT PCI-Ex card and am trying to add a 9400GT PCI card to my setup, to run a total of 4 monitors, but all I can get is the PCI bridge error (10) in device manager. It shows that the proper drivers are installed, but it "cannot start".

From what I've read, Windows 7 doesn't support video cards that use different drivers. So, is Microsoft trying to force people to use SLI or Crossfire or what?

At my company, about half of the employees have a 5 monitor setup. Typically running integrated video + a Quaddro card. This will keep us from upgrading to Windows 7 until the issue is resolved.

Does anybody have any suggestions for getting around this?
