My PC has 5 PCI slots, all full. When I replace the old sound card with a new one the computer will no longer boot. It turns on but the screen never even comes on to show bios loading or anything. If I remove any one of the PCI cards (except for video obviosly) the computer runs fine even with the new sound card. I need all 5 cards (video, wireless ethernet, USB, ATA133 IDE, and sound) so I don't know what to do. Any help would be greatly appreciated.
