problem installing a new graphics card

[golfnut]

i have an amd athalon 64 processor@2.4ghz with 2gb memory and the motherboard is a gigabyte GA-K8N51GMF-9

i have bought an Nvidia GeForce 8400gs 512mb card
the problem is my pc is using on board graphics and i cant seem to get it to disable the on board graphics so i can get this other card running
i put the card in as told to do so and fired up the pc was told it shud say when on the windows screen new hardware found this did not show at all
i then proceeded to install the software for the card then reset pc with vga cable which still did nothing i've then gone into bios settings to tell the pc to go on pci slot only which has resulted in nothing

any help would be appreacited thank you

either that i have been sold a faulty card

Windows will use whichever display it finds first as the primary, Go into the Nvidia control panel (right click on the desktop and select it) then using the "SET UP MULTIPLE DISPLAYS" you can select if you want to use more than one display, which mode you want to use it in, and which is the primary.

If you don;t have nvidia drivers installed in the bios sometimes you can either turn off the internal display or make the PCI/e display the priority, but not all bioses allow you to do that.

Check the hardware manager for both display adaptors

Confirmed, in ADVANCED BIOS FEATURES you should have a INIT DISPLAY FIRST set that to PEG

This is a fault I have come across and it is a motherboard bios issue. Maybe update? the bios should offer priority to PCI E rather than PCI though. What are the bios options for display adapter

I have had machines that do this. You turn it on and it displays from onboard turn it off and it displays from GFX card. As long as the psu remains plugged into the mains and switched on the system will then reboot or start up displaying from GFX card but as soon as you unplug it it reverts to onboard.

Most modern motherboards will detect a card and totally disable the onboard.

Because the board is Nforce and the card is Geforce its not trying to run some sort of hybred sli is it?

Yep I checked the manual and PEG is the PCI/e option

Init Display First
This feature allows you to select the first initiation of the monitor display from which card when you
install a PCI card and a PCI Express VGA card on the motherboard.

• PCI Slot Set Init Display First to PCI VGA card.
• Onboard VGA Set Init Display First to onboard VGA.
• PEG Set Init Display First to PCI Express VGA card.(Default value)

Always worth a bios update though

You are right in that it should switch to the new card, as I said in post #2 though it could be that the onboard is set as primary hence the device manager query.

Could be that the bios predates the series 8 cards so doesn;t detect it as a vga card (it is a 939 socket board) but it should not try SLI

I know there are a few boards out there that are capable of hybred 2 gpu solutions onboard gfx running with a card but I don't even recall if its ATI or Nvidia does lol Its not something I would ever consider trying.
