Keep the monitor connected to the onboard, enter the BIOS, disable the onboard, return the shared memory back to the system & change the 'initial display' setting to the PCIe slot. Save your settings, then shutdown. Make sure your new card is fully seated in it's slot, then connect the monitor to the card. Boot up & install the nvidia drivers.

BTW, with all the decent/cheap gaming cards available these days, why did you settle for an 8400GS? I assume you bought the card for gaming, right? If so, it was a poor choice.

Hello Jam,

Thanks for the reply, i've tried all that u mentioned i anyhow could not find the disable on board video as u mentioned in my Bios Version 1011 006 beta Asus P5gdc-v deluxe, i disabled the shared memory option saved the bios and connected the monitor to the card " Same result " no display my pc starts normally though, now the weird thing is when i plug the monitor back to the onboard the display is back though i have selected the display priority to PCIe/PCI

another thing i noticed while setting the boot display priority to PCIe, disable the shared memory, save the bios and restart ( without changing the monitor back to card ) i re-enter the bios and check the shared memory it auto selects 8MB ( not sure if this means anything )

what can b the problem for the Card not showing display. once i plug the card in the fan on the card does starts spinning still no display

help plz

No matter how you configure the BIOS, the onboard will always display the POST screen & allow you to access the BIOS. But if you changed the 'initial display' to PCIe, the video card should take over when windows starts to load.

The 8400GS is a weak card so the power supply shouldn't be a factor. Make sure the card is fully seated. Pop it in & out of the slot a few times. If it still doesn't work, it could be the card is defective. And if that's the case, return it & replace it with something better. The 8400GS is not a gaming card.
