On your computer's motherboard.
no no really
if the card goes into the slot completely without being forced, then its in the right slot
normally the motherboard have 1 slot for video card.
The Slot Type
video card
An AGP video card.
The bus, for example: PCI-Express (x1, x4, x16) or PCI, or AGP. To imagine this for yourself, it's the slot in your pc, on your motherboard, with that slot, your video card will have to be compatible with. this means, you can't insert a PCI-Express Video Card into an AGP slot. :)
If the video card(s) in question has/have a power slot on them (might be a 4 or 6 pin slot) they MUST have power. Reason being, the power going to the video card power key components for the video card which without, will not work at all.
I believe you can get PCI, PCI-X or AGP video capture cards. Each card would need the corresponding slot, such as an AGP card would require an AGP slot.
An AGP slot is a post-PCI/pre-PCIx graphic card interface bus. It was a step up from the PCI video cards, but were phased out with the PCIx standard.
