Right now the only thing i have in a pci slot is my sound blaster audigy gamer. I wanted to try putting an internal modem in there because i heard they are faster than my external. I put in the modem and the system never found it in any of the pci slots. My sound card works fine and i tried putting it in the other slots and none of them found it either. Somewhere along the line my PCI slots that weren't being used got messed up and i can't use em now. I've been using the same slot for my sound card since i got my comp so i dunno when they stopped working. Any help would be appreciated.
