I know this might be a dumb question and idea but would a PCI card work in a PCI-e x16 slot? The reason I ask is because my motherboard only has one PCI slot and I have 2 PCI cards, network adapter and a sound card. For the network adapter, I was using a usb adapter but I can't get that to work since I reinstalled Windows. So now I am back to using the PCI adapter. I am thinking about hooking up directly to the router so I can eliminate the use of an adapter. I just don't know how many feet it will take since I am on the top floor and the router is in the basement. Anyways, I know some of you might say use onboard sound but I don't care for the onboard sound that much. I guess my x-fi card has spoiled me. I thought about buying a pci-e x1 sound card but with my motherboard, it looks like it will not fit in either slot, definitely not the top one. Someone on another forum says pci-e x1 cards will work in x16 slots. I really don't want to buy anything else just yet. Long story short, would a PCI card work in a PCI-e x16 slot? Is there any risk of damage? I would not force anything if it didn't fit. Would the computer recognize it as a video card? Would it work the same as it would in a PCI slot?
