Onboard video IS NOT A CARD!
A CARD is removable and plugs directly into a slot built into the mboard!
"...which i disabled before i physically installed
Huh? In almost all cases, there is no mboard jumper or setting in the bios Setup to disable onboard video.
You can set Primary Video or Initialize Video First or similar to PCI, PCI-E, and to on onboard video or similar, but doing that doesn't disable it. Installing a video card in mboard slot MIGHT automatically disable onboard video.
Apparently your mboard has
Two (2) PCI slots
One (1) PCI Express x1 slot .
Is the 8400GS a PCI card, or a PCI-E X1 card??
(There ARE 8400GS PCI-E X1 cards).
(e.g. http://www.tigerdirect.ca/applicati... )"
NOTE - a PCI-E X1 card will work in a PCI-E X16 slot, but a PCI-E X16 card cannot work properly in a PCI-E X1 slot and you probably cannot physically plug it into a PCI-E X1 slot anyway (unless you hacked off the inner end of the slot)!
Installing a PCI video card may not disable the onboard video automatically, but installing a PCI-E x1 video card might.
(Installing a video card in an AGP or PCI-E X16 slot usually does, but your mboard has neither of those.)
ATX PSs are always powering ATX mboards in some places, including some contacts in the mboard ram and card slots, even when the computer is not running, as long as the PS is connected to the mboard and it's receiving live AC power.
Did you unplug the computer, or otherwise remove the live AC power to the computer, when you plugged in the card?
If you didn't, you may have damaged thecard!
Are you sure the card is all the way down in it's slot, and was all the way down when you first booted the computer with the card in it??
Go into the bios Setup and set Primary Video or Initialize Video First or simlar to PCI if the video card is PCI, or to PCI-E or PCI-E x1 if it's a PCI-E X1 card, save settings.
Apparently your computer comes with a 300 watt power supply.
A 8400GS PCI card requires the system has a minimum 300 watt power supply. A 8400GS PCI-E X1 card probably requires the same.
If you still have the original power supply, it will just barely handle the 8400GS card.
If you don't have it....
