any luck on this one ?
can anyone from Intel help us out ?
I have this same problem
system: Intel DH55HC motherboard + i7 870 + 8GB
video: Leadtek GT 430 PCIe + EVGA 8400 GS PCI
os: Windows 7 64-bit
windows will only recognize the card which is set to start as the primary video device in the BIOS
and the "PCI standard PCI-to-PCI bridge" will always fail to start under windows
"This device isn't using any resources because it has a problem"
this is a brand new PC
I did a fresh Windows 7 64-bit install
then installed the Intel motherboard drivers from the included CD
if i plug in only the PCIe video card everything works fine
its when i have both cards plugged in do I get the error on the "PCI standard PCI-to-PCI bridge" in Device Manager
I did also at one point see an error: "this device cannot find enough free resources that it can use"
under I/O resource allocation
if i have only the PCI card plugged in I can see the PCI Bridge takes the resource
0x0000E000-0x0000EFFF PCI standard PCI-to-PCI bridge OK
.. and I get no errors
but when I plug in the PCIe card as well I can see this card takes over some of the same resource range .. and i then get the PCI Bridge error
0x0000E000-0x0000E07F NVIDIA GeForce GT 430 OK
Both of these cards use the same NVIDIA drivers - which I have installed ... but I still get the PCI Bridge error
I have now tried every combination of 4 different PCIe cards and 2 different PCI cards
from the same and different manufacturers ... and have now given up
have ordered an ATI Eyefinity card which I will pick up today .. which will let me run the 3 monitors i want !
I believe this is a flaw in the Intel motherboard .. as these video card combinations work perfectly fine in 2 other PC's i have - with ASUS and Gigabyte motherboards
something I have noticed:
when the PCI card is set to primary in the bios
Windows 7 can infact detect the type of PCIe card which is plugged in - and will install drivers for it.
But the PCIe card doesn't seem to function properly - ie. noting happens if i plug in a monitor to any of its ports (usually W7 would auto extend the desktop)
and the additional screen option doesnt appear in Display Settings.
