Hi Allin. You need Windows 98se or later for reliable USB operation, but some older motherboard's BIOS doesn't give reliable operation even with a PCI USB card. There have been some serial port card readers made, but these are difficult to find. Users of Sony Memory Stick can get a device to fit into a floppy drive that can read the Stick, but this is about £60. I don't know of a similar device for other formats. I had this same problem and eventually gave up and fitted a new motherboard and processor.
