|You don't have to be on the computer in question to go to Delll and download drivers.|
Using the make/model information from the computer in question you should be able to go to a "downloads" for that particular model and get the drivers you need. Put them on your memory stick and then take it over to the computer needing the drivers and plug it in. Go into Device Manager and install the drivers for the device in there pointing to the drivers you have on the memory stick.
I would advise burning those drivers to CD to hang onto in case you ever have to reinstall the OS on that machine again in the future.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
