Assuming the devices are 'plug and play', then windows is supposed to recognize them and supply the appropriate drivers. If you don't have boxes, manuals or any info as to what the peripherals are, then open up the computer and take a look at the cards. You could get lucky and the make/model of the peripheral may be on the card; then you can go the mfg. website and d/l the latest drivers. Otherwise, you'll have to guess.
