I had this problem described below. I went to Best Buy where I purchased the video card and the computer. I even bought a newer better power supply 550W from what came with the computer. No one has been able to help, any help would be greatly appreciated.
My computer: HP Media Center m3480f running Windows Vista 64-bit
Video Card that came in computer: Dual Display NVIDIA PCI Express 16 - 8500 GT
The new video card I bought to add a 3rd monitor: NVIDIA PCI 8400 GS
The GeekSquad guy ( don't get me started ) told me my two options were to purchase the PCI Express 1 from somewhere on the internet, or I could just take out the OEM PCI modem, and replace with a PCI video card to run my third monitor.
I removed the PCI modem that came installed on my HP Media Center m3480f. I replaced it with an additional Nvidia GeForce 8400 GS to run a third monitor. When I install the card, it causes issues and will not recognize my video drivers.
When I go into device manager, it has a yellow triangle and excalamtion point need to two items.
1: Intel(R) G33/G31/G35 Express Chipset PCI Express Root Port - 29C1
2: Intel(R) 82801 PCI Bridge - 244E
It gives me an error code (12), says there's not enough resources for the system device.
I am running the standard equipment that came with the HP Media Center m3480f other than the new power supply.
I have attempted to change in the BIOS what the primary video source is, I have tried PCI, PCI Express 16, but not PCI Express 1 - as I do not have a video card to fit that slot.
My question is which is the best way to free up a resource for it to recognize the card?
Secondly, is this even possible to do? The video card that came with the computer, and the new card I bought are both 8-series NVIDIA cards so they use the same driver and I have the drivers installed correctly.
My two monitors work great without the PCI card installed in the bottom slot. When I plug in the additional PCI card, I can no longer see the NVIDIA control panel, and it will only run one monitor.
Any help with this would be great!
Thanks in advance.
